Chapter 4 - Using Your Modem
Multi-Tech Systems, Inc. MT5634ZPX User Guide 22
Operating Your MultiModemZPX
If you’re an experienced modem user, you may only want to check your modem’s settings
for data compression, error correction, and so on. You’ll find you can get moving quite
quickly by using a terminal window (you may use HyperTerminal in Windows) to issue the
AT&V<cr>
command. This command will list your modem’s current configuration, the
stored (user) profiles, and the stored telephone numbers. If you come across a setting
you’re unsure of, refer to the AT Command Reference Guide for AT commands and S-
Register explanations and defaults.
Your MT5634ZPX can be controlled by issuing AT commands and setting S-Registers.
Since your MultiModemZPX default settings use a traditional modem set to make a dial-
up call to a remote installation where the call is answered automatically—you shouldn’t
need to change the current configuration.
In operating your MultiModemZPX, 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
• Launch a data communications or Dial-Up Networking session through a set of
modem configurations that you select and then associate with a target telephone
number.
