Configuring your Modem using a Terminal program

Getting a Terminal Program Ready

If you are not using the ISDN configuration utility that is packaged with the Omni TA128,
you will need a terminal program to from which to configure the unit. The Omni should
work with any asynchronous terminal program that can communicate directly with one of
the communication ports on your system. If you do not know how to use a terminal
program, please refer to the instructions that came with the terminal program.
Make sure the program is set up to communicate with the COM port that the Omni
TA128 is connected to. You can check to see if the DTR LED is on when the terminal
program is active. In most cases, if the terminal program is active and ready to
communicate with the port that the Omni TA128 is connected to, it will activate the DTR
signal. This will cause the DTR LED to light up. If DTR is not ON, you will need to
check the program's settings.
The communication speed can be set to anywhere between 1,200bps and 460,800bps,
but 115,200bps is a good default value. The Omni TA128 will automatically adjust its
speed to match your communication speed.
Once the terminal communication program is ready, you can type a simple command to
see if the Omni TA128 responds to it.
Type:
AT<Enter>
Omni TA128 should respond:
OK
Type:
ATI<Enter>
Omni TA128 should respond:
1281
Type:
ATI1<Enter>
Omni TA128 should respond:
Omni TA128
7607 (Firmware checksum will change based on your firmware version)
OK
Once the Omni TA128 accepts the commands that you typed, it is ready to be
programmed and ready to operate with your ISDN network. If you do not see any
response from the device, go over your installation procedures again or contact the
ZyXEL Technical Support.
