ATS18 Test Timer
S Register 18 contains the length of time, in seconds, that the modem will perform tests initiated
with any of the &T commands.
You can terminate any test by issuing an AT&T0 command, or by allowing the time in the Test
Timer to expire.
Placing a value of 0 in S Register 18 disables the Test Timer, forcing you to use an AT&T0
command to terminate tests.
Examples
ATS18=30 Terminate test after 30 seconds
