1. Look at the Status bar at the bottom of the
HyperTerminal window.
It should read “9600 8-N-1.” The Control port has a fixed

Steps
TO CHECK THE BAUD RATE ON THE DATA PORT
■ From HyperTerminal (probably on the Control port),
type:
AT+IPR? and press Enter.
The modem should respond with the following:
+IPR: 38400 (or whatever the current baud rate is)
38400 is the default setting for the Data port. If you
change the baud rate setting for the modem’s Data port,
be sure to configure HyperTerminal accordingly.
Note
You can enter AT+IPR? on either the Control port or the Data port, but
it always responds with the baud rate of the Data port.
