S15 Bitmapped Register
Selects the data bit(s) you want the modem set on, and sets S13 to the total of the Value
column. For example, ATS13.0=17 enables bit 0 (value 1) and bit 4 (value 16).
S16 Bitmapped Test Register
Selects the data bit(s) you want the modem set on, and sets S13 to the total of the Value
column. For example, ATS13.0=17 enables bit 0 (value 1) and bit 4 (value 16).
S18 Test Timer
Sets the length of time, in seconds, that the modem conducts a test before returning to the
command mode. When this register value is zero, the test will not automatically
terminate. The test must be terminated from the command mode by issuing the &T0 or H
command.
S19 Inactivity Timer
Sets the duration, in minutes, for the inactivity timer. The timer activates when there is
no data activity on the phone line; at time-out the modem hangs up. A setting of 0
disables the timer function.
S19=0 disables the timer.
