2. In HyperTerminal, click OK to accept the settings.

HyperTerminal automatically attempts to connect to the modem, and the modem powers on when HyperTerminal asserts the RS-232 DTR signal. Once it has connected you should see the following within a few seconds:

SELF TEST RESULT: OK

Note: The SELF TEST RESULT message appears only during modem power-up. If the Diagnostic cable has been connected and its switch is set to “POS 1 DTR to GND,” then the modem has already powered up. In that case, proceed to step 3 without waiting for the message.

3. Type AT and press Enter.

If the HyperTerminal port connection is correctly configured, the modem should respond with:

OK

Tip You can connect to the modem at any time by clicking HyperTerminal’s

Connect button.
