Modem Power Reset:
Optional. If this is enabled, then the SC200 will attempt
to reset a non-operating modem by turning its power
supply off and on using digital output 2.
Modem Set Up String:
The string sent to the modem on reset.
The modem AT command should not be included as it
is automatically sent. The Auto-Answer Rings
parameter is also sent, so it does not need to be
included here. For complete details of appropriate
commands, consult your modem documentation.
Modem Auto Answer Rings: Number of rings before an incoming call is answered.
Setting this parameter to zero disables incoming calls
(the modem can still be used for alarm reporting).
