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.
Software Guidelines
An indicator enclosed in less than/greater than signs represents a
specific character in the appropriate character set, ASCII or
EBCDIC.
