Section Four
S18 — Test Timer
Range 0-255 seconds
Default 0
Sets the length of time the modem conducts a test before returning to the
command mode. If this register is zero, the test will not automatically
terminate; the test must be terminated from the command mode by issuing
an &T0 or H command.
S24 — Sleep Inactivity Timer
Range 0-255 seconds
Default 10 seconds
Sets the length of time, in seconds, that the modem will wait before
entering power down sleep mode. The time is reset by any data activity or
telephone line activity. A value of zero will disable power down sleep
mode.
S25 — Delay to DTR
Range 0-255 (hundredths of a second)
Default 5
A change in /DTR (ON-to-OFF) that persists for a period shorter than the
value held in S25 is ignored by the modem while it is in data mode.
S30 — Inactivity Timer
Range 0-255
Default 0 (disabled)
Determines the length of time, in ten-second intervals, that the modem will
wait before disconnecting when no data is sent or received. In MNP or
V.42 mode, any data transmitted or received will reset the timer. In other
modes, any data transmitted will reset the timer. The inactivity timer is
inoperative in synchronous mode.
