F,
f
Fast dialing speed
When you want to tone or pulse dial using faster signaling rates, you can
use this command. The F command forces the Modem to dial while in the
automatic originate mode at 10 digits-per-second for touch-tone or 20
pulses/second (pps) for pulse dialing. The RATE
=
S line on the listing will
then show RA TE
=
F.
Note: The fast dialing speed command is mainly used in touch-tone
dialing. Fast pulse dialing is seldom used. When you experience
difficulty in fast pulse dialing, set the rate to slow.
G,
g
Forced carrier detect toggle
This command is used to turn on and off the forced carrier detect signal
(FCD). When the FCD is ON, the DCM-7 issues a forced carrier detect sig-
nal to the computer upon power-up, and the CARRIER DETECT indicator
lights. When the FCD is OFF, the DCM-7 issues a carrier detect signal to
the computer when it detects a true carrier signal on the telephone line and
lights up the CARRIER DETECT indicator.
The default condition of this command is set by DIP switches 2 and 6. The
G command is disabled when DIP SW 2 is ON.
If
you input G when the
switch is ON, the Modem informs you by showing:
FORCED CD SWITCH IS ON
You can check the status of the FCD at the FCD
=
parameter listing by us-
ing the L command.
I, i Ring/retry change command
This command allows you to change the answer on n rings or retry n times.
The I command displays the intermediate menu. When you press Q) , the
DCM-7 prompts:
ANSWER ON 1-9 RINGS OR CR FOR NO CHANGE
=
The cursor (if used) will be positioned after the
=
sign and await your in-
put. If you press
(ENTER )
instead of typing a number, the DCM-7 assumes
that you want to keep the already programmed number of rings. Only a nuni""
ber between 1 and 9 or the (
ENTER )
key is a valid entry. All other entries
are not accepted. If you reply to the prompt with an invalid entry, the DCM"7
will echo the key (display the key you just entered, if displayable) and ask
the question again.
