Autobaud

Autobaud is the process where the modem determines the DTE speed. The modem determines the AT Speed during the AT entry process (either Idle or Online Command State) and during the entry of the A/ command (except in FAX modes).

In FAX mode (when +FCLASS=1 or +FCLASS=2), the modem may or may not autobaud while off hook.

The modem normally recognizes commands sent by the DTE at 300, 1200, 2400, 4800, 7200, 9600, 14400, 19200, 28800, 38400, 57600, 115200, and 230400 bits/s. Register S144, if supported, can change this list of speeds.
