match that at which the last AT command was
issued.

Parameters 0 or 1
Default none
If the user enters the command mode from the data mode by issuing the
escape sequence, or as a result of an ON-to-OFF transition of DTR with
the &D1 option in effect, the user may return to the data mode without
terminating a call by issuing the O0 command. This command may also
be used to force a retrain. If the modem is on-hook, then the modem
behaves as if it went off-hook to originate without actually taking the relay
off-hook.
Examples
ATO0 Causes the modem to return to the data mode
ATO1 Causes the modem to return to the data mode and
to initiate a retrain when operating at 2400 bps.
Also, adjusts the transmit level at 2400 bps to the -
Un setting.
