Using AT Commands to Verify Modem Response

Use AT commands to make sure the Model XM128 modem responds, and follow these steps:

1.Type the command AT and press [Enter].

You should receive the following response:

OK

2.Type the command ATI and press [Enter].

You should receive the following response:

1291

3.Type the command ATI1 and press [Enter].

You should receive the following response:

NETGEAR XM128 ISDN Digital Modem xxxx: V x.xx 7607

OK

In the first line, x designates the country or region of operation and the firmware version number. The second line is the firmware checksum (which changes based on your firmware version).

Communication Speed Setup

Make sure the program is set up to communicate with the COM port that is connected to the Model XM128 modem. In most cases, when the terminal program is active and ready to communicate with the connected port, the DTR signal is activated and the DTR LED lights. If the DTR LED is off, check the terminal program settings.

The communication speed can be set between 110 bits per second (bps) and 460.8 bps, but 115.2 bps is a good default value. The Model XM128 modem automatically adjusts its speed to match the communication speed you set.
