V.25 bis Autodialer

Autodialer Command Strings and Parameters

Most command strings for the autodialer include two parts: the command itself and the parameters that follow. For the purposes of this chapter, parameters can be telephone numbers or anything appropriate to V.25 bis as described in the following text. Parameters are separated by semicolons.

For example:

PRN a; nnn . . . n

where a= the phone number address in memory and nnn...n= the phone number. The a and the nnn...n are both parameters. Not all commands have parameters. For example the CIC command has no parameter.

•Each response below is considered an individual message by V.25 bis conventions. For example, a dial command with intermediate call progress enabled (BISYNC mode ASCII/EBCDIC character set) is:

From computer To computer

<sy><sy><stx>CRN<sp>(205)555-0124<etx> <sy><sy><stx>VAL<etb>

•V.25 bis commands can be in one of these data formats:

ASYNC BISYNC SDLC NRZ SDLC NRZI
