AT and V.25bis Command Sets

V.34bis Series Standalone & Rackmount Modems
The international command set for modem control is defined by the CCITT
and termed V.25 bis. Some countries require V.25 bis to be the only means
of controlling a modem, and some require the modem to respond to V.25
bis commands but allow other command sets to be used. For controlling a
modem by synchronous commands, there is no other serious contender for
a de facto standard.
The V.25 bis command set has very limited capacity to control a modem
except for the basic dialing functions. For most modem settings, the AT
command set will be found more useful and provides for easier
configuration of the modem options. The details of the commands and
responses of the V.25 bis command set follows.
Note: The V.25 bis EIA signaling must be configured using either AT
commands or the front panel. The AT commands to enable
V.25 bis signaling are:
AT &C2
AT %C3
AT %D2
This configuration will allow the DSR, CD and CTS EIA signals
to function as specified in the V.25 bis specification.
