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.
