Appendix B
When a carrier signal is detected, the Modem goes ON LINE and sends the
result code:
CONNECT (or 1)
The result code ON/OFF condition is determined by the Q command (DIP
Switch 4). The type of the code is determined by the V command (DIP Switch
3).
R, r Reverse mode command
Use this command to call and establish communication with an originate-
only modem. When R is entered, the Modem enters answer mode
automatically after it dials the telephone number.
Example:
AT D(111)123-0009R (ENTER) Wake up!
Originate
a
call.
Change to answer mode and wait for
carrier.
P, p Pulse dialing (default)
The P command sets the Modem to pulse dialing mode.
If
your phone line
is rotary type, input P at any point in the telephone number sequence. You
can change to pulse dialing mode from touch-tone dialing mode by entering
ATP any time you want.
When the type of dialing (pulse or touch-tone) is not specified in the com-
mand line, the Modem defaults to the type used in the last command. Pulse
dialing is fixed at 10 pps (pulses per second).
T, t Touch-tone dialing
When T is added to the dial command, the Modem is set to touch-tone dial-
ing mode. Use register Sll to change the speed of touch-tone dialing.
Pause
When you use the Modem in an office or anywhere that requires an access
code to get an outside telephone line, you will need to add a pause before
dialing the number that follows. Insert the , command between the access
code and the telephone number.
The pause duration is determined by register S8. The default pause duration
of I comma is 2 seconds. You can accumulate the duration by using multi-
ple commas.
