Using the AT Command Set
I-modems are controlled using AT commands.
To send AT commands to the I-modem, connect a computer with an EIA-232 serial port to
the I-modemÕs serial port. The computer must be running a communications software
package.
Before you can send any AT commands to your I-modem, you need to put your communi-
cations software in T
erminal mode. In Terminal mode, what you type is sent directly to the
I-modem.
