Command: &M n Communications Mode
Values: n = 0–3
Default: 0
Description: This command determines the DTR operating mode. The modem
treats the &M command as a subset of the &Q command.
&M0
Selects direct asynchronous operation. Command sequence
&M0\N0 selects normal buffered mode, but command
sequence \N0&M0 selects direct mode. This is because the \N0
command is analogous to the &Q6 command.
&M1 Selects synchronous connect mode with asynchronous offline
command mode.
&M2 Selects synchronous connect mode with asynchronous offline
command mode. Same as &M1, except that &M2 enables DTR
dialing of directory slot 0. The modem disconnects if DTR is
low for more than the period stored in S25.
