Modem DTR Mode
This governs whether the modem port DTR line is permanently asserted or
switched on only when the port is sending characters. The DTR line is not
needed for use with smart modems. To change the mode, type the following
command:
SET MODEM DTR {SWITCHED | CONTINUOUS}
The default mode is CONTINUOUS.
Phone Numbers 1 and 2
Phone number 1 is the phone number that the unit will dial first when trying to
send out an alarm message. The phone number must be specified if a dial-out
mode is chosen. Phone number 2 is an optional second phone number that the
unit will dial if Phone number 1 is busy or does not answer.
To set phone numbers, type the command:
SET PHONE 1 XXX-XXXX <RETURN>
or
SET PHONE 2 XXX-XXXX <RETURN>
where XXX-XXXX is the phone number. Any string of up to 20 characters is
acceptable, provided the modem can interpret it. This string is preceded by the
letters ATDT or ATDP depending on whether tone or pulse dialing is selected.
Any special dialing prefixes should precede the number entered here, such as
“9," for dialing out from a PBX, or any special sequences for disabling Call
Waiting. For example:
SET PHONE 1 9, 555-5555 <RETURN>
Ring Count
This mode determines the number of rings the modem at the unit end will
answer. In order to use this command, the modem must be connected to the unit
and preferably be on hook. To set this value, type the command:
SET RINGCOUNT X <RETURN>
where X is the number of ( 0 - 9) rings. Zero (0) means Do Not Answer. The
default is 1.
