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, 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 TA 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 TA is connected to, it will activate the DTR signal. This will cause the DTR LED to light up. If the DTR LED is not ON, you will need to check the program’s settings.
The communication speed can be set to anywhere between 2,400bps and 460,800bps, but 115,200bps is a good default value. The TA 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 TA responds.

AT<Enter>
TA should respond:

Type:
ATI<Enter>
TA should respond:
1281
