Local Modem Self-Test

To run a local self-test:

1.Put the Modem into interactive or local mode. Refer to the communications software manual for this information.

2.Enter AT [ENTER]. The Modem will respond with OK. If you cannot see the letters you entered, the local Modem echo is OFF. To turn on the local Modem echo, enter ATE1 [ENTER].

If double characters appear on the screen, both the Modem and software are set to local echo ON. To set the Modem to local echo off, enter ATE0 [ENTER].

If 0 appears on your screen in place of OK, the numeric form result codes have been enabled. To select textual result codes, enter ATV1 [ENTER]. The Modem will respond with OK.

If the Modem does not respond:

•Ensure that the communications software setup procedure was run after the Modem was installed. Setup must be run each time the Modem is installed.

•Check that the COM port address of the serial port is identical to the software COM port assignment.
