S Registers
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 |
