AT Command Set Description
Digicom SpA
&I2
= constant speed is enabled. Upon connection,
“CONNECT” will appear followed by the data
interface speed.
&I3
= same as &I1 with parity reconstruction
AT&M
This command selects synchronous or asynchronous mode of
operation.
&M0
= The modem is programmed for asynchronous
operation.
&M1
= The modem is programmed for synchronous
operation.
It is disconnected from the DTE with criterion DTR;
the standby transition of this criterion causes the
modem to be disconnected.
&M2
= The modem dials the number stored in memory
location N0 when DTR is raised; communication is
synchronous. The modem hangs up the call and
returns to command mode when DTR is lowered.
&M3
= The modem is programmed for synchronous
operation.
The CTS remains OFF until the connection is over.
Note:
As soon as the command &M3 is given, the modem will
lower the CTS; therefore should it be used to program an
asynchronous terminal that uses criterion CTS (ON) to send the
commands, it is convenient to give this command only at the end
of programming or to ignore criterion C106 (CTS) to the
terminal.
