Is Your MultiModemZDX Ready for Use?

As soon as you have connected power to the modem, if you're an experienced
modem user, you may simply want to check your modem's settings for data
compression, error correction, and so on. You may find that you can get moving
quite quickly if you just issue the AT&V<cr> command. This command lists how
your modem is currently configured.
If you're a novice, please continue to the next sections of this chapter.

Operating Your MultiModemZDX

You control your MultiModemZDX by issuing AT commands and setting S-
Registers. Right now your MultiModemZDX 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.
In operating your MultiModemZDX 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. Entering AT
automatically sets the modem's serial baud rate to match your computer's and also
sets the modem's parity. It also clears the modem's command buffer.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 .

Simple Operations

You can dial by using the ATD command and the phone number of the modem with
which you wish to connect, e.g., ATD6127853500. Your modem will dial the
number; a "scrambling" noise is heard as the modem negotiates the kind of
connection it can make, and once the modems have settled on a common
connection, a connect message on your computer's video is displayed. To hang up
a call, enter ATH0<CR>. Your modem will return on hook, just as if you had
returned a phone's handset to its cradle. Your video now displays OK , signifying
that your modem is ready for your next command.
