Establishing a communication
session
Any terminal emulation program can be used to create a
communications session that will allow you to issue AT
commands to the modem. This section describes how to use
HyperTerminal, a program typically installed with Windows,
to establish a session with the modem.
To establish the communications session:
1. If the modem is not already connected to a serial port on
your computer, connect it.
2. If open, close Watcher (or any other program that commu-
nicates with the modem).
3. Launch HyperTerminal. (Depending on your version of
Windows and how it was installed, you can launch the
program by selecting
Start > Programs > Accessories >
Communications > HyperTerminal
.)
4. Enter any name and select any icon in the Connection
Description window and click
OK.
5. Select the COM port to which the modem is connected
(usually
COM1) in the Connect using field, and click OK.
6. Select these port settings:
· Bits per second 115,200
· Data bits 8
· Parity None
· Stop bits 1
· Flow control Hardware
Click OK.
To verify that the communications session is functional, enter
AT. The modem should respond with OK.
