Dialling

Dialling will commence as soon as the DTR signal is asserted (an OFF-ON transition occurs). Your modem will not generate response codes when synchronous mode 2 is selected. All call progress is indicated by your modem’s speaker (the M command controls the operation of your modem’s speaker). As soon as your modem connects to a remote modem it will assert the DSR and DCD signals.

Hanging Up

Your modem will hang up and return to quiet asynchronous mode if the carrier is lost for longer than the period defined by S Register 10 or if DTR is lowered.

Answering Calls

Whenever your modem receives an incoming call it will assert the RI signal. The terminal may accept the call by asserting the DTR signal as soon as the number of rings defined by S Register 0 is reached. The terminal may refuse the call by keeping DTR low eight seconds after the number of rings in S Register 0 is reached.

Your modem will not dial the stored number in response to DTR being asserted between the time an incoming call is initially detected and the call being cleared.
