V.25bis Command Set
To enable V.25bis commands use the AT*I1 command.
For synchronous applications, the modem is permanently set in normal
situations for use with one application. Save the desired settings in the
power-on profile, and the modem will be initialized to synchronous
mode (&M3) with V.25bis command enabled (*I1) when powered
on.
A special command RST is provided to get the modem back to
asynchronous AT command mode from V.25bis mode. You can enter
this RST command in either synchronous or asynchronous V.25bis
mode.
