Online Command State
In the Online Command State the modem maintains the connection with
the distant modem, but it treats DTE signals as commands. The modem may
enter the Online Command State as a result of the patented Hayes Improved
Escape Sequence with Guard Time or as a result of a DTR ON-to-OFF transition
when certain combinations of &Dn and &Qn are in effect. The Online
Command State only exists in the Smart Mode. Refer to the &Dn
and &Qn commands.
Received data patterns, RDL requests, and equalizer retrain requests from
the distant end are honored while the modem is in the Online Command State.
