S18 Modem Test Timer: (0)
S18 specifies the amount of time that the modem will conduct one of the
loop back tests (&Tn). After timing out, the modem returns back to
Command Mode. Setting S18 to zero disables the Modem Test Timer;
the loop back test must be terminated by issuing the appropriate escape
sequence followed by an ‘AT&T0’ or ‘ATH’.
