Appendix D - Command Modem Commands
for your dialing.
An example of combining pulse and tone dialing
could involve a PBX system where 9 had to be
pulse-dialed first, then the rest of the number
tone-dialed after pausing for a second dial tone.
The number would be dialed by entering
ATDP9,T5551212 and hitting Return. (The
comma causes a pause, which is explained
later in this appendix.)
Q0-1 Result CodesEnabled or Disabled
It may be desirable to disable the Result Codes
(see V command) altogether in certain
applications, such as computer-controlled auto
dialing. The Q command is used to do this, with
ATQ1 disabling the Result Code transmissions
and ATQ0 (or ATQ) enabling them. If you do not
select either method, the factory default setting
will enable the Result Codes to be sent.
R Forcing an Answer Tone in the Dialing
If you wish to dial up another modem that is in
the originate mode, it is necessary that your
modem be in the Answer mode to initiate the
“handshaking” and establishment of a
connection. This is done automatically when the
command letter R is entered at the end of a
dialing command. When this is done, the
command modem will switch to the Answer
mode as soon as the number is dialed and
transmit a carrier signal to the other modem.
For example, entering ATD5551212R and hitting
Return would cause the number 555-1212 to be
dialed and cause the command modem to
transmit a carrier signal at the end of the dialing
sequence.
