Loopback Test

1. Connect a microphone and speaker to the MultiModemZPX. To avoid feedback, make sure

the microphone and speaker are well separated; better yet, use a headphone instead of a

speaker.

2. Select Start, point to Programs, point to Accessories, and click HyperTerminal.

3. Click Cancel in the Connection Description dialog box.

4. In the HyperTerminal terminal window, type AT&&S and press ENTER. This command causes

input from the microphone to be looped back to the speaker.

5. Speak into the microphone; you should hear your voice on the speaker or headphone.

6. Type ATZ and press ENTER to reset the modem.
