result code:

The result code ON/OFF condition is determined by the
Q
command (DIP
Switch

The type of the code is determined by the
V
command (DIP Switch

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
S11
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
1
comma is
2
seconds. You can accumulate the duration by using multi-
ple commas.
