Tandy DCM-7 Operation Manual page 39

Appendix A
A, a Answer mode operation
The Modem is defaulted to operate in originate mode when first powered
up. The A command is used to change the DCM"7 from an originate mod-
em to an answer modem. Use the answer mode when you want to receive
a call from a modem which is operating in originate mode. The M command
(manual/automatic toggle) determines whether the Modem will wait for the
telephone to ring (auto answer) or seize the telephone line as soon as you
exit the command receptive state with the X (manual answer).
You can enter this command repeatedly. There is no harm in entering A when
the DCM-7 is already in answer mode. You rriay want to put A in your ap-
plications software to be sure the DCM-7 is in answer mode before running
the program.
C, c Clear memory
The C command clears the DCM-7's memory and resets all the parameters
to the default values. There is no need to follow the C command with the
execute command (X), because the memory is cleared immediately when
©
is
pressed. After this command is issued, the DCM-7 returns to off-line mode.
Use the wake-up command (*)to enter the command receptive mode.
You can use the C command when you have changed several parameters and
you do not want to go back and change each one. It also saves you from
having to cycle the power switch OFF and ON.
D, d
Enter dialer programming mode
Use this command to enter the dialing parameter setting mode. When you
enter the D command, the dialer memory is cleared and the DCM-7 waits
for the following subcommand entries:
0-9,
*,
#
(Telephone number and code)
These must be valid digits that can be dialed on the phone. The * and
#
are used only in the touch-tone dialing mode for special service.
P, p Dial pause subcommand
Wait here for 2 seconds before dialing the rest of the digits. You may need
to enter this command to access an outside line when your phone is located
behind a PBX.
R,
r
Pulse (rotary) dial subcommand
