Owner's Manual

Operating Your MultiModemZPW-PCI

You control your MultiModemZPW-PCI by issuing AT
commands and setting S-Registers. Right now your
MultiModemZPW-PCI is set up for the most typical user
application, that is, as a traditional modem set to make a dial-up
call to a remote installation where the call is answered
automatically; therefore, you shouldn't need to change the
current default configuration. (If however, you know that your
application does not follow this profile, please refer to Chapter 3
for AT Commands and S-Registers.)
In operating your MultiModemZPW-PCI it is likely that you will
use your data communications software to either:
• enter "terminal" mode, where you can "speak most directly"
to the modem by issuing AT commands, or to
• launch a datacomm session through a set of modem
configurations which you select and then associate with a
target telephone number. Once you have created, saved,
and named this set of information according to your
connection needs and your datacomm software's
conventions, the software then simplifies your dialing
because you needn't reconfigure your modem, nor run the
risk of mistakenly keying-in incorrect information.
Either way, you need to understand that an AT command is the
method by which your modem is controlled, and must therefore
prefix nearly all commands. AT stands for attention, and alerts
the modem that a command follows. You may enter these
commands with either upper- or lower-case characters. Once
you're in terminal mode, enter AT followed by <CR> to check
whether your modem is operational. If everything's fine, your
modem will respond OK .
