BS BACKSPACE code
The BS code is simply an editing feature for the D command. If you are
typing a number and make an error, press @ID to delete the last character
typed. If you press
@[)
immediately after .selecting the D command, a
?
will appear to indicate an error condition.
A total of up to 40 digits and symbols that follow the D command can be
stored and dialed by the DCM-7. The stored number will be kept in memory
until you turn off or reprogram the DCM-7 by entering Dor C. Use the list
command to confirm the number.
The pulse dialing mode is the default condition and the Modem applies the
dialing mode of the previous call
if
R nor T does not precede the telephone
number.
The DCM.:7 allows you to mix signaling types in a telephone number. For
example, the sequence DR234333PPT-(lll)-123-4567 says to pulse dial the
number 234333, pause for 4 seconds, then tone dial the number 1111234567.
The dashes, parentheses and space are ignored by the DCM-7 during dialing.
If you have problems when using touch-tone and/or the fast dialing rate,
your telephone line may not be suitable for these modes. Use rotary dialing
and/or the slow dialing rate. Refer to dialing speed commands F and S.
E, e Echo disable/ enable toggle
This code is used to disable or enable the "echo" function. When enabled,
the echo supplies feedback to your computer's display. When disabled, data
you send to the DCM-7 will not be echoed to the computer display, includ-
ing the parameter settings. The display will not show anything, even if you
type L. If the echo feature is disabled, the DCM-7 will appear -dead, but ac-
tually it is working normally.
The default (power-up) setting of echo function is the echo enable.
