To return to asynchronous operation:
• Type: AT&M0 and press ENTER
Dialing
Your computer must be in asynchronous mode before dialing
commences. To begin dialing use the D command. Response
codes sent to the computer depend upon the settings of the X,
V
and Q commands. As soon as a connection can be
established, your modem will assert CTS and enter
synchronous on-line state. If connection cannot be made, your
modem will hang up and return to asynchronous local
command state. Character echo and response codes should not
be selected when synchronous communications are used. Use
the E0 and Q1 commands to disable character echo and
response codes.
As soon as your modem has completed dialing it will examine
the state of the DTR signal. If DTR is asserted your modem
will go on line in synchronous mode, otherwise the modem will
hang up and return to asynchronous local command state.
Data should only be transmitted once DCD, DTR and CTS have
been asserted. Your computer should not assume that if CTS is
asserted then it is safe to begin transmitting data — your
modem will keep CTS asserted whenever it is in local
command state.
Hanging Up
Your modem will hang up and return to asynchronous mode if
carrier is lost for longer than the period defined by S Register
10 or if DTR is lowered after the &D2 command has been
issued.
