Terminal Adapter AT Commands
You can configure the terminal adapters using AT commands just as
you would configure an analog modem. Use this method if you prefer
to work with AT commands or if you have a special requirement not
addressed by either of the configuration utilities.
To configure the TAs with AT commands:
1. Start a data communication program and select the TA COM ports
to be configured.
2. Referring to records made for your system, enter AT commands in
the terminal window of the data communications program.
3. When you finish, use the &W command to save your new
configuration and to select it to load automatically when the ISIHP
is turned on.
4. Close the data communications program. For more information, see
the chapter on AT Commands and S-Registers in this manual.
