Converse with terminal or logical unit (CONVERSE)

For most terminals or logical unit types, a conversational mode of communication can be used. The CONVERSE command is used for this purpose and means that the 3650 application program communicates with the host processor. If this option is not specified, the 3650 application program cannot communicate with the host processor. In general, the CONVERSE command can be considered as a combination of a SEND command followed immediately by a WAIT TERMINAL command and then by a RECEIVE command. However, not all options of the SEND and RECEIVE commands are valid for the CONVERSE command; specific rules are given in the syntax descriptions for different devices. The TOLENGTH option is equivalent to the LENGTH option of the RECEIVE command, and the FROMLENGTH option is equivalent to the LENGTH option of the SEND command.
