Function
numbers the modem dials. The characters A B C D # * apply only to tone dialing. The
characters are ignored for pulse dialing. The characters A, B, C, and D may be disabled
in countries prohibiting their use.
Pulse dialing. P selects the PULSE method of dialing. This command may be issued
within a dial command or as a separate command. The default method of dialing is
PULSE.
Originate a call in ANSWER mode. R causes the modem to handshake in ANSWER
mode so it can originate a call to an originate-only modem.
Dial a stored telephone number. The equals command S=0 instructs the modem to
dial a stored telephone number if the modem has nonvolatile memory (EEPROM) to
store country parameters. Stored numbers may contain any dial digits or modifiers.
Telephone numbers may be stored using the &Z command. If the modem does not
feature nonvolatile memory (EEPROM) and the S command is issued, an ERROR result
code is returned.
Tone dialing. T selects the TONE method of dialing. T can be issued within a DIAL
command or as a separate command. The default method of dialing is PULSE.
Wait for dial tone. W causes the modem to wait for a dial tone before proceeding. If no
dial tone is detected, the modem hangs up the telephone line and returns the NO
DIALTONE result code.
Delay processing of next character. A comma (,) causes the modem to pause for the
length of time in S-register S8 before processing the next character in a dial string.
