Electronic Information Exchange By Larry Jordan If you are interested in turning your PC into an information exchange machine when you are not using it for other applications, you have five choices. You can buy one of three commercially available packages; you can obtain a public domain Remote Bulletin Board System (RBBS) by downloading it from this system or you can write your own software. The three commercially available packages are HOSTCOMM, SPS-BBS and Remote Access; Wes Merchant can set up a group purchase on any of these packages if enough people are interested. Summary descriptions of the packages are provided below. Package name: HOSTCOMM List price: $179 (utilities are extra) Software Type: Personal Host Vendor: N.F. Systems P.O. Box 76363 Atlanta, GA 30358 Summary Description: This package supports messages sent from a caller to the SYSOP and from the SYSOP to General Mail or a specific caller. HOSTCOMM is password controlled for access to directories of software that can be downloaded or uploaded, but it only allows ASCII files to be uploaded to or downloaded from the system. The software allows the SYSOP to set up three special purpose programs that can be run from a remote terminal; access to these programs is also password controlled. Programs that can be run remotely are limited to TTY line-at-a-time types that do not use full memory mapped screens. Electronic mail and order taking special purpose remote operation programs are available from the same vendor. Package name: SPS-BBS List Price: $99.95 Software type: Bulletin Board Vendor: Small People Software P.O. Box 732 College Park, MD 20740 Summary Description: This is a message based bulletin board system that allows callers to send messages to other callers or retrieve messages from other callers. The software also allows callers to download software from the system or upload software to the system, but it only supports the sending or receiving of ASCII files. SPS-BBS is a program originally written on a Radio Shack TRS 80 and was not adequately revised for operation on an IBM PC. For example, it sends many ASCII control characters out the communications port that confuse users by cluttering up messages. Package name: Remote Access List price: $50 ($79 Full Screen) Software type: Remote access Vendor: Custom Software P.O. Box 1005 Bedford, TX 76021 Summary Description: This package was written specifically for the IBM PC, and allows a caller, through password control, to run the PC from a remote terminal. It comes in two versions: one for operation from a remote dumb terminal and one for operation from another IBM PC. The dumb terminal version only allows the remote operation of TTY line-at-a-time software such as dBase II or the BASIC Compiler. The PC full screen version allows remote operation of both TTY software and memory mapped software such as Wordstar or VisiCalc. Remote Access also supports limited electronic mail -- the user can leave a message for the SYSOP or the SYSOP can leave messages for specific callers (essentially the same as HOSTCOMM). Remote Access also allows both ASCII and binary file transfer; the binary file transfer is done using the XMODEM protocol. The public domain RBBS comes in many varieties depending on who took a cut at improving it last. One version that Jim Fry, Scott Loftesness, Gary Horwith, Rich Schinnell, Dorn Sticle and I have "improved" is available for download on my system, but you should be warned that this system may contain bugs. It does support XON/XOFF communication speed-matching, XMODEM file transfer, 1200 baud, auto-paramter detection/switch, and electronic mail, but it is written in interpreter BASIC. As new improved versions of RBBS come available, they will be placed on my system for you to download and use. The final option of writing your own electronic information exchange software is not recommended unless you have a lot of free time and many friends who will call it to help work out the bugs. Actually, I am surprised that software houses have not jumped on the electronic information bandwagon with host and bulletin board systems, but most of them have chosen to develop smart terminal software instead because of the greater sales potential. I think they are short sighted. As PC's proliferate there will be a big market for good host software.    potential. I think they are short sighted. As P
