Once installed, these commands remain resident in memory, available for your use, until you either reboot your computer or execute the resident Quit command. The operation of the various resident conferencing commands may be reviewed by selecting the "Tutorial" choice in the Main Menu. Since the commands remain resident when other programs are used, they do not have to be reloaded if you switch between different programs or if you take part in more than one conferencing session. If you should accidently try to install a second copy of the commands, the program will recognize that the commands are already loaded, and will produce an error message. "Phone" Menu Choice Information The "Phone" menu choice allows you to make new entries or to modify existing entries in a phone directory maintained by the program. It also allows you to automatically dial phone numbers in the directory or to dial new phone numbers entered at the time you want to make the call. When you select the "Phone" choice, the Phone Menu appears. Oper- ation of this menu is similar to that of the Main Menu. Descriptions of the menu operations and choices are available through use of the help screens accessed with the "H" and "F1" keys. "Files" Menu Choice Information The "Files" menu choice allows you to transmit or receive files of any kind over a connection, with a proprietary protocol. The protocol used speeds up the transfer of most files significantly, and includes error control features that make it highly unlikely that an uncorrected transmission error will occur. However, since it is impossible to guarantee perfect transmission, you are advised to retain a backup copy of all transmitted files. It is not necessary that the source and destination files be on the same drive and directory, or even that they have the same name. How- ever, use of the same file name may facilitate subsequent conferencing in some cases. For phone line operation, file transfer always proceeds from a voice conversation, and returns you to voice when completed. "Settings" Menu Choice Information The "Settings" menu choice permits you to change the values of some program parameters to suit your computer system configuration and preferences. It is essential that you set the proper communication port (COM1 or COM2) before you attempt to use the "Files" facility of the SETUP program to transfer any files, and before you use the "Commands" menu choice to load the resident conferencing commands. Selection of the "Settings" menu choice will cause the Settings Menu to appear, and the current settings to be displayed. If you have never changed them, these settings will be the default values. The default communication port is COM1. If you have changed these values previously, the settings shown will be the last ones that you saved. "Tutorial" Menu Choice Information The "Tutorial" menu choice provides explanations of the various resident conferencing commands that are loaded when the "Commands" menu choice is selected. While some context-sensitive help is avail- able during conferencing, it is far less descriptive than the Tutorial. Also, you will probably not want to study such material while you are online for a conferencing session unless absolutely necessary. The Tutorial also contains additional information on the use of the SETUP program to prepare for a conferencing session. It is strongly recommended that you review the Tutorial thoroughly before beginning a conferencing session. "Exit" Menu Choice Information The "Exit" menu choice returns control of your computer to the DOS operating system. You may subsequently load another program and execute it in the usual fashion, even with the conferencing commands installed, since these commands are implemented as a "resident" program. The SETUP program may be reloaded again if, for example, you want to use the "Phone" or "Files" capabilities. However, you will not need to load the conferencing commands again unless you reboot or use the resident Quit command to remove the commands. "Help" Menu Choice Information The "Help" menu choice displays general information on the operation of the SETUP program. Additional information is available through context-sensitive help by pressing the "F1" key when different menu choices are highlighted or when a program message appears. Also, the Tutorial facility provides information on the SETUP program as well as on the resident conferencing commands. "Invalid Keystroke" Message This message indicates that your last keystroke was not one of those that are effective during Main Menu operation. The valid keystrokes are summarized in the information screen that will appear when you strike any key at this time. "Commands Already Installed" Message This message reminds you that the resident conferencing commands have already been installed. They do not have to be installed again until you reboot the computer or use the resident Quit command. "Configuration File Corrupted" Message This message warns you that the configuration file HTASETUP.CNF was found to have invalid parameter settings data. As a result, some or all of the program parameters have been set to their default values. Check the current program settings, revise them if necessary, and save a new copy of the configuration file. "Program Set to Default Parameters" Message This message informs you that SETUP did not find the HTASETUP.CNF file and has set the program settings to their default values. This will always be the case the first time that you use the program, since it is shipped without a HTASETUP.CNF file, allowing the SETUP program to self-install. Use the "Settings" menu choice to customize the pro- gram parameters for your system configuration. Otherwise, if you have loaded SETUP from a backup copy but did not also copy the HTASETUP.CNF and HTAPHONE.DIR files, you may want to exit SETUP and copy the files now in order to use any saved settings or di- rectory entries. "SETUP Cannot Find Its Files" Message The SETUP program expects to find the files CMDSET.EXE, HTASETUP.CNF, and HTAPHONE.DIR on the same drive and directory that it was loaded from. This message was produced because the first of these three files was not found. Some possible causes for this are: (1) You did not load SETUP from the default drive and directory. To load the resident commands or to use your saved settings and phone directory, you must exit SETUP, change the default drive and direc- tory to the one containing SETUP, and then reload it. (2) You loaded SETUP from a backup copy on a disk or directory which does not also have a copy of the CMDSET.EXE file. You should copy all files (including HTASETUP.CNF and HTAPHONE.DIR) onto your back- up disk and directory. "Commands File Not Available" Message The resident commands could not be loaded because the file containing the commands could not be read. Some possible causes for this are: (1) You have removed the diskette containing the COCOMPUTE program. (2) The diskette drive containing the COCOMPUTE program is not ready. (3) You did not originally load the SETUP program from the default drive and directory. In this case you should have received the warning "SETUP cannot find its files". You must exit SETUP, change the default drive and directory to the one containing SETUP, and then reload it. The "Autodial" Menu Choice The "Autodial" menu choice is used to dial a number from your direc- tory, or one you enter in the scratch pad. To dial from the directory, select an entry in the usual way. Otherwise, move the highlight to the scratch pad area and enter the number to be dialed. When you press re- turn, your modem will dial the number, using the currently selected dial code (which may be blank). If you want to use one of the other dial codes, change the dial code selection before you autodial. You may pick up the phone before, during, or after your modem dials the number. Hitting a key after dialing is complete will cause the modem to hang up, allowing you to talk. If you hit a key before this, dial- ing is aborted. A number dialed from the scratch pad is not discarded after dialing so that it may be modified and/or redialed if desired. The "NewNumber" Menu Choice The "NewNumber" menu choice is used to enter a new name and phone number in the first unused directory line. The name or phone number is entered by typing the contents into the scratch pad. Active editing keys include the left and right arrows, the backspace and delete, and the home and end keys. The insert key toggles editing between the in- sert and overstrike modes. The return key completes the entry process. The length of names and numbers is limited by the scratch pad size to 35 characters. Since the provided directory fields are smaller than this, some of the contents may not be visible when they are transferred to the directory. However, the full entry is saved and may be inspect- ed or edited with the "Revise" menu choice. Of course, the auto- dialer dials the entire number, not just the visible part. The "Revise" Menu Choice The "Revise" menu choice is used to edit or enter contents in a name, number, or dial code field of the directory. First, select the field to be edited by moving the highlight and pressing return. New entries may be placed in the directory by moving the highlight to the first un- used line. The contents of the selected field (if any) will be placed in the scratch pad for editing. Active editing keys include the left and right arrows, the backspace and delete, and the home and end keys. The insert key toggles editing between the insert and overstrike modes. The return key completes the entry process and the scratch pad contents are placed in the directory. At that point, you may move the highlight to another field to be edited if desired. Otherwise, press the return key again to return to the Phone Menu. The "Delete" Menu Choice The "Delete" menu choice can be used to remove a directory or dial code entry. Simply move the highlight to the unwanted entry and press return to complete the deletion process. If you choose the Delete menu choice accidently, use the Esc key to return to the Phone Menu. If you accidently delete entries (or if you make other changes that you have second thoughts about) simply exit the Phone Menu without saving your changes. Your directory will revert to its previous contents. The "Move" Menu Choice The "Move" menu choice can be used to change the position of a direc- tory entry. Use the highlight to point to the entry that you want to move. When you hit the return key, the entry is placed temporarily into the scratch pad. Then point with the highlight to the desired new position for the entry and press return again. The moved entry will be placed at the highlight, and the current and following entries will be moved down one line to make room for it. The "Sort" Menu Choice The "Sort" menu choice can be used to sort the directory entries alphabetically, according to the contents of the name field. Upper and lower case letters are not distinguished, and numbers are considered to come before letters. In order to guard against an accidental sort, you will be asked to confirm the selection before the sort is performed. The "Codes" Menu Choice The "Codes" menu choice is used to change the dial code that will be used when you autodial. The current selection is indicated by a high- light on the dial code label, and can be changed with the up and down arrow keys or the corresponding label number key (i.e., 1, 2, or 3). Use the dial codes to specify frequently used dialing prefixes and/or suffixes. The codes are entered with the use of the Revise menu choice. Legal characters include the digits, and the characters *, #, T, P, ",", and N. The N is used to show where the phone number is to be inserted. For example, the dial code "P9,TN,,,,,213 555 1212 1234" pulse dials a 9, waits 2 seconds, tone dials the inserted number, waits 10 seconds and dials the credit card number. Blank dial codes are of course also permitted, in which case only the number is dialed. The "Exit" Menu Choice The "Exit" menu choice returns you to the Main Menu. If you have made any changes to your directory, you will be given the choice of saving or discarding those changes. Thus, if you accidently delete an entry or make some other unwanted changes, you may choose not to save the new directory version. Then, when you reenter the Phone Menu screen, your previous directory version will be restored. The "Help" Menu Choice The "Help" menu choice displays general Phone Menu information. General Directory/Autodialer Information Phone numbers entered into the directory can include the digits and the symbols * and #. The comma (",") may be used to introduce a two sec- ond delay in dialing, as when waiting for a second dial tone. The letters T (or t) and P (or p) can be used to specify tone or pulse dialing. Any other characters are considered to be punctuation and are ignored. Names in the directory can be anything at all. Most of the directory maintainance features require that you point to a directory entry by moving a highlighted bar. This can always be done in two ways. The first way is to use the arrow keys to move the high- light in the desired direction. The second is to press the key corres- ponding to the label (the letter or number on the left side) for that entry. The second method is generally, of course, much faster. Invalid Keystroke Use the left or right arrows to move the highlight, and the return key to select. Otherwise, type the upper case letter in the desired menu choice. Directory Changes Could Not Be Saved The phone directory changes could not be saved in the file HTAPHONE.DIR on the default drive and current directory. Some possible reasons for this are: (1) The diskette drive is not ready. (2) The diskette is write protected. (3) The diskette is full. Correct the problem, reenter the Phone Menu, and try again. The "Look" Menu Choice The "Look" menu choice is used to display files from your specified directory. You may enter an optional drive, directory path, and file name in the usual way, including the global characters * and ?. The files found will be displayed along with their sizes. The "Filespec" Menu Choice The "Filespec" menu choice is used to name the file that is to be transferred. The usual editing keys may be used in entering the name. The specification consists of a disk drive, directory path, and file- name with extention. If the drive and/or directory are omitted, the defaults are used. A typical specification might be entered as "c:\direc\subdirec\file.ext" (without the quotes). See the DOS man- ual for further information. The receiver of a file does not have to give it the same name that it has on the sending computer (although this may be desirable in some cases), and he may place the file on any of his drives and directories. The "Direction" Menu Choice The "Direction" menu choice is used to indicate whether you will be transmitting or receiving the file being transferred. The "Ready" Menu Choice The "Ready" menu choice instructs your computer to check that your disk drive and modem (if used) are set to perform the file transfer. Use of this option enables you to identify and correct potential prob- lems before you attempt to go online to perform the transfer. Since you remain in voice contact when the "Ready" choice is executed, it is a good practice to always use the "Ready" choice before the "Go" choice is executed. The "Go" Menu Choice The "Go" menu choice causes your computer to go online and transfer the specified file. The sender and receiver must execute "Go" at about the same time. While the file is being transferred, its progress is shown in the status display. If many blocks are repeated, the line is probably too noisy and you may want to redial. If you change your mind about a file transfer after it begins, the transfer can be aborted with the Esc key. If modems are used and your program is set for hangup delays, you will be reminded to hang up your phone before the modems begin to connect. If the modems fail to connect, or when the transfer is complete, you may switch from data back to voice. The "Exit" Menu Choice The "Exit" menu choice returns you to the Main Menu. The "Help" Menu Choice The "Help" menu choice gives you general information about the file transfer capabilities of this program. General File Transfer Information The "Files Menu" choices enable you to send or receive a disk file over a connection, starting from a voice conversation. Decide which file will be transferred. The sender then identifies the file with the "Filespec" menu choice. The receiver enters the name under which he wants the file to be saved on his computer, which need not be the same name. Tell your computer whether you will be the one sending or receiv- ing by using the "Direction" menu choice. The "Ready" menu choice minimizes potential problems by pre-checking your disk and modem. Then you use "Go" to go online and transfer the file. If modems are used, you will temporarily lose your voice connection during the transfer. Invalid Keystroke Use the left or right arrows to move the highlight, and the return key to select. Otherwise, type the upper case letter in the desired menu choice. Cannot Open File to Send The most likely causes for this message are: (1) The file name is not correctly specified (see the DOS manual). (2) The file does not exist (check your directory). (3) The diskette drive is not ready. Cannot Open File to Receive The most likely causes for this message are: (1) The file name is not correctly specified (see the DOS manual). (2) The diskette drive is not ready (3) The diskette is write protected. Turn On or Reset Modem Your modem is not responding to commands. If it is an external modem, check that it is turned on. If so, reset it by switching it off and on again. If this does not eliminate the problem, check that the modem is set to operate in its Hayes-compatible mode and that you have set the modem data rate to the correct speed in the program settings. Modem Compatibility Problem Your modem is not responding properly to commands. Check that it is set to operate in its Hayes-compatible mode. No Carrier Received from Other Modem The modems failed to connect. The most likely causes are: (1) You were both set to "Send" or to "Receive". (2) You were not both set to the same modem data rate. (3) One of you waited too long (more than a few seconds) to "Go". (4) One of you didn't use "Ready" to check your disk and modem, and they weren't ready to go. Now that you are back in the voice mode, correct the problem, and try again. Transfer Aborted If the abort was unintentional, the most likely causes are: (1) There was not enough room on the receiver's disk. (2) The line was so noisy that a block could not be transferred after five tries. (3) A disk read or write error occurred. It may take a few seconds for both computers to recognize the abort. At that point, you may take corrective action (redial if the line seems very noisy) and try again. Connection Failed The connection between the two computers could not be established. One of you may be set to the wrong comm port. If you are using a cable, make sure that the connectors are wired so that transmit data on each side goes to receive data on the other. The "Rate" Menu Choice The "Rate" menu choice is used to select the line data rate. Be sure that the other conferee has their line set for the same rate. The "Line" Menu Choice The "Line" menu choice is used to indicate whether your computer is connected to the other with a modem or wire type of connection. The "CommPort" Menu Choice The "CommPort" menu choice is used to set the proper serial port. The available serial ports are COM1 and COM2. The choice between these is generally made at the time that you install a serial adapter or an internal modem. COM1 is the usual default. If you do not know which port your modem or wire is connected to, you should consult the documentation for your serial port or internal modem. If you are using a modem, you may receive a "resetting" message when going online. If the modem is turned on, it is likely that you are set to the wrong port. The "Warn" Menu Choice The "Warn" menu choice permits you to turn the program's "pickup warnings" feature on or off. If your modem and phone are connected in parallel (see figures below), you must hang up when the modem goes on- line in order to avoid interfering with modem operation. Then later, when the modem goes offline and hangs up, the phone connection will be broken unless you have already picked up the phone. The warning "pick up phone & hit Esc key" will prevent this from occurring. If your mo- dem and phone are connected in series, you do not need to hang up, and you may choose to have the pickup warnings turned off. Ŀ Ŀ Ŀ Ŀ SERIES: phone modem wall PARALLEL: phone modem wall The "Delay" Menu Choice The "Delay" menu choice permits you to turn the program's "hangup delays" feature on or off. If your modem and phone are connected in parallel (see figures below), you must hang up when the modem goes on- line in order to avoid interfering with modem operation. It is impor- tant that you do not hang up before the modem goes off hook, but also that you do hang up before the two modems connect. The hangup delay feature will display the message "hang up now" and will introduce a small delay so that you can easily hang up in time. If your modem and phone are connected in series, the hangup delays may be turned off. Ŀ Ŀ Ŀ Ŀ SERIES: phone modem wall PARALLEL: phone modem wall The "1Trig" or "2Trig" Menu Choice The "Trigger" menu choices enable you to customize the program with respect to the keys used to trigger your computer to respond to the resident conferencing commands. The choice of allowed trigger keys in- cludes the left and right shift keys, the Esc, Ctrl, and Alt keys, and any of the function keys. You can select the same key for both trigger keys, in which case only that key needs to be pressed to trigger your computer. Otherwise, both trigger keys must be pressed and held. Remember that the second trigger key to be pressed is never seen by the application program that you are running. If you choose to use only one trigger key, do not use a key such as the left and right shifts, since you will need to use it in running the application. The "Monitor" Menu Choice The "Monitor" menu choice enables you to direct the program to use the desired display mode. This is particularly important if your sys- tem is configured with more than one monitor. If you have not speci- fied a particular display mode, the program will default to the display mode in effect when the program was loaded. When you save a new dis- play mode setting in the HTASETUP.CNF file, the specified display is used the next time that you start the SETUP program. If you change monitors and find that your display no longer works prop- erly, erase the HTASETUP.CNF file from your current directory, reload the SETUP program, and reset and save the program configuration parame- ters with the new display correctly specified. The "Save" Menu Choice The "Save" menu choice instructs your computer to save the current settings in a configuration file on your disk. Then, the next time you load the SETUP program from the disk, the configuration file will be read and the program settings will be initialized to your saved values. The configuration file is kept on the same disk and directory as the one from which the SETUP program was loaded. If this is a diskette, it is important that you do not remove it before selecting the Save choice, and this diskette must not be write protected. The "Exit" Menu Choice The "Exit" menu choice returns you to the Main Menu. Any settings changes that you made will be effective if you subsequently load the resident conferencing commands. However, unless you have used the "Save" menu choice to save these changes in the configuration file, the changes will not be effective the next time that you load the SETUP program. The "Help" Menu Choice The "Help" menu choice provides some general information on the use of the Settings Menu to change the program settings. General Program Settings Information The Settings Menu and its supporting capabilities permit you to change various parameters that affect the operation of the SETUP program and the resident conferencing commands. One of them, the setting of the communication port, must be attended to if your line uses COM2, since COM1 is the default option for this program. The other settings are also more than a matter of convenience. See the context-sensitive help screens for their meanings. Note that some settings changes take effect the next time you load the SETUP program or the resident conferencing commands. If the commands have already been loaded when you make a settings change, you must re- move the commands with the Quit command or by rebooting. Then, reload the commands and the new settings will be effective. "Invalid Keystroke" Message This message indicates that your last keystroke was not one of those that are effective during Settings Menu operation. The operation of the Settings Menu is similar to that of the Main Menu except for the Esc key, which in this case returns you to the Main Menu. "Cannot Save Settings" Message This message indicates that the settings cannot be saved because the configuration file, HTASETUP.CNF, cannot be accessed as required. Some possible causes for this are: (1) Your diskette drive is not ready. (2) Your diskette is write protected. General Program Information The SETUP program provides a set of capabilities that may be used to prepare for a conferencing session. These capabilities are invoked by selecting the corresponding menu choices and, in some cases, by responding to program prompts. For example, selecting the menu choice "Commands" results in the installation of the conferencing commands in memory. This operation is always necessary prior to conferencing. Other menu choices may not always be required. Detailed information on specific menu choices and program messages can be obtained by striking "F1" when the menu choice is highlighted or when a program message appears. Also, the "Tutorial" menu choice provides additional information on the operation of the SETUP program as well as the conferencing commands. "Access" Menu Choice Information The "Access" menu choice enables you to operate your computer as a data terminal. You can easily send any ascii characters with values between 0 and 127 out your serial port. At the same time, any arriving ascii characters will be displayed on your screen. You can also send a break signal. The primary application of the Access screen is to facilitate making connections through serial-data devices. Such devices include certain types of data-switches, data-PBXs, central-office LANs, and non-Hayes compatible modems. Once you have made the connection to the other PC, you can use CO-COMPUTE's wire mode to cocompute or to transfer files. These operations will not disturb the connection. When your session is completed, you can use the Access screen to drop the connection. The "Online" Menu Choice The "Online" menu choice allows you to send and receive any ascii characters with values between 0 and 127. Printable characters gener- ate the ascii values between 32 and 126 (see any ascii table). Usually these are the only characters required. The other ascii values can be generated by Ctrl shifts. Values 1 to 26 are generated by Ctrl-A to Ctrl-Z. Control shifts for the remaining values are 0:2, 27:[, 28:\, 29:], 30:6, 31:-, 127:BkSp, where the first entry in each pair is the ascii value and the second is the key. Note that these definitions are not arbitrary but follow the IBM keyboard codes. A break can be gener- ated by hitting any function key. All ascii values echoed or received are displayed by the corresponding keystroke except for "Enter", "BkSp", and "linefeed" (Ctrl-Enter), which move the screen cursor instead. Ctrl is shown as an upward-directed block arrow. The "Break" Menu Choice The "Break" menu choice sends a break signal to the serial data con- nection. Such signals are sometimes used to control data switches and other communication devices. You can also send a break signal while you are operating the Access screen terminal by hitting any of the function keys. CO-COMPUTE's break signals are approximately 2 seconds long. The "Params" Menu Choice The "Params" menu choice causes the Access Settings menu screen to appear, allowing you to examine and change the parameters used during Access screen terminal operation. The "Exit" Menu Choice The "Exit menu choice returns you to the Main Menu. The "Help" Menu Choice The "Help" menu choice provides some general information on the operation and use of the Access screen. General Access Settings Information The Access Settings screen allows you to set parameters used in Access screen terminal operation. These parameters are independent of those that CO-COMPUTE uses for its other operations. This allows you to meet the special settings needs of some communications switching devices. You may also specify whether or not typed characters should be echoed to the terminal screen by CO-COMPUTE. The parameters set will be used when you return to the Access screen terminal. However, changes will not be saved unless you use the "Save" choice to write the new Access settings to the configuration file. The "Rate" Menu Choice The "Rate" choice lets you specify the data rate used in sending and receiving characters with the Access screen terminal. This rate is independent of the one used by CO-COMPUTE for its other operations. The latter data rate is specified in the Settings screen. The "Data" Menu Choice The "Data" choice lets you specify the number of data bits used to represent each transmitted or received character when you are using the Access screen terminal. If you are using odd or even parity, this choice should be set to 7. The "Parity" Menu Choice The "Parity" choice lets you specify the type of parity (if any) used in sending and receiving characters with the Access screen terminal. The "sTop" Menu Choice The "sTop" choice lets you specify the number of stop bits used in sending characters with the Access screen terminal. The "eCho" Menu Choice The "eCho" choice specifies whether or not CO-COMPUTE should echo typed characters to the screen when you are using the Access screen terminal. If your communications device echoes characters, you should turn off CO-COMPUTE's echo setting to avoid having each typed character displayed twice. If your communications device does not echo charac- ters, you must turn on CO-COMPUTE's echo setting in order for typed characters to be displayed. The "Save" Menu Choice The "Save" choice will save your Access parameter settings to the configuration file HTASETUP.CNF. Then, the next time that you load the SETUP program, the Access parameters will be set to the values saved. The "Exit" Menu Choice The "Exit" choice returns you to the Access screen. The "Help" Menu Choice The "Help" choice gives you general information on using the Access Settings screen. General Access Screen Information The Access screen allows you to operate your computer as a simple data terminal. To operate the terminal, choose the "Online" choice from the menu. Then, when you type, the characters that you type will be sent out your serial port. Likewise, any characters that are received from your serial port will appear on your screen. When you are fin- ished using the terminal, use the Esc key to return to the Access menu. If all you want to do is send a break signal, you can do so with the "Break" menu choice. You may change certain communication parameters used during Access screen terminal operation by using the "Params" menu choice.
