Modem Command Reference
Section Four
Modem Command Reference
This section of the manual describes the AT commands that the
Trumpcard modem supports. This information includes command
parameters, defaults, result codes, and often examples.
These commands cannot be entered (and sent) to the modem from the
operating system command line. You must use a communications
software package to talk to the modem. Your communications software
may handle all of the communications with the modem for you — you may
never have to issue an AT command yourself. Refer to your
communications software documentation for more information.
Also included in this section is a list of the S registers and their functions.
At the end of the section is a list of the facsimile commands supported by
the Trumpcard data/fax modem. These commands appear for reference
only — you cannot operate the facsimile manually.
