CHAPTER 4: Manual Dial and Automatic Answer
4) Abort Timer.
Answer Mode: When OH (Off Hook) comes on, the called modem
starts a forty-five-second timer and waits for a carrier signal from
the originating modem. If carrier is not detected within this period,
the modem disconnects (hangs up) and is ready for another call.
Originate Mode: The abort timer functions the same as in answer
mode, except that the timer begins after the modem has
completed dialing, instead of when it first goes off hook. It is
possible to change this forty-five second wait period to any other
value (from 0 seconds up to 255 seconds), or to disable the timer
completely by re-configuring S-Register S7 (see Chapter 6.)
5) Inactivity Timer. Causes the modem to disconnect if no data is
transmitted or received for a specified time. The timer is restored
any time a character is passed through the serial port in either a
send or receive state. This timer runs in both normal or reliable
connections and is controlled by S-Register S30. The Inactivity
Timer can be disabled by setting S30 to 0, which is the factory
default setting.
