Making a Call with Your
Modem
The dial command (D) is used to initiate a call. When the
modem receives this command, it goes off-hook (connects the
modem to the phone line so that a call can be made), and dials
the telephone number entered. Going off-hook is similar to
picking up a telephone's handset.
Dial command strings contain the dial command, dial
modifiers, and the telephone number. A dial modifier tells the
modem to perform additional tasks when dialing a telephone
number.
The following can be used as dial modifiers:
T – Touch-tone dialing. Any digit 0—9, * , # , A, B, C, or D can
be dialed as tone.
P – Pulse dialing. Only the digits 0—9 can be dialed in Pulse
Dial mode.
- , ( ), and Space. These characters are ignored by the dial
string and can be included in the dial string to enhance
readability.
, – Pause. Causes the modem to pause before processing the
next character in the dial string. The length of this pause is
determined by the value held in S-Register S8, the Pause
Time configuration option.
W – Wait for dial tone. Modem waits for a second dial tone
before processing the dial string. For example, if you must
dial a 9 to reach an outside telephone line, the W modifier
delays the modem from dialing until it receives a second
dial tone for the outside line.
R – Reverse Dial mode. Causes the originating modem to
send out an answer tone once it no longer detects
ringback. (Ringback is the ring you hear at the originating
site when making a call.) The R parameter must be the
last character in the dial string. For correct operation, at
least one ringback must be detected; therefore, the remote
modem should be placed off-hook into originate mode on
the second ring or later.
