Dial a call.
immediate
The D command requires an ASCII character string to specify
the telephone number to be dialed as follows:
For voice calls, the valid characters are limited to ''*'', ''#'',
and digits 0 through 9. Voice dial commands with invalid
characters are accepted and the invalid characters are
ignored; only the valid characters are dialed.
For data calls, the character string may include any ASCII
character with the following restrictions:
If the letters ''t'' (uppercase or lowercase) is typed as
the first character following the D command, or as the
first character of a stored number when a ''t'' does not
follow the D command, the 7400B Plus will delete the
character.
For example, if you want your dial string to be the
mnemonic ''TEXAS,'' you must type the ''T'' twice (the
first ''t'' may be uppercase or lowercase), producing
the command line:
atdtTEXAS (
The ''t'' following the D command will be discarded
and the string ''TEXAS'' will be sent to the PBX as a
dial mnemonic (the PBX must be administered to
recognize this mnemonic as the representation of a
number to be dialed).
Mnemonic dialing is valid for data calls only.
Note:
The PBX may interpret certain non-alphanumeric
characters as commands and perform an unexpected
action, if you did not intend to send the command to the
PBX. Consult the documentation for your PBX to
determine which characters may be interpreted as
commands.
The dial modifier s=n, where n may be a number from 0
through 3, will cause the 7400B Plus to send the contents of
its respective telephone number storage location to the PBX
as the telephone number. For details on how to use this
feature, refer to ''Storing a Telephone Number'' in Chapter
3, "Configuration and Operation."
