Making a Call from the Data Port

You can make a data call by entering AT commands in HyperTerminal connected to the modem’s Data port. You will be able to see the packets streaming, just as a demonstration that the modem can make a packet data call.

Steps

TO MAKE A PACKET DATA CALL USING AT COMMANDS ON THE

DATA PORT

 

 

1. Make sure HyperTerminal is set up on the PC connected

 

to the modem’s Data port, as described in Setting Up

 

HyperTerminal to Talk to the Modem on page 2-15.

 

2. If HyperTerminal is connected to the modem on its

 

Control Port, you must disconnect it before you can type

 

AT commands on the Data port. You can leave the cable

 

plugged into the Control port, but disconnect from the

 

Control port using HyperTerminal (click the Phone icon).

 

3. In HyperTerminal, initiate the call on the Data port by

 

typing ATD#777.

 

#777 is a special number that tells the modem to establish

 

a packet data call. HyperTerminal responds with

 

CONNECT. You will see random characters streaming on

 

the screen, with an initial tilde “~” character to indicate

 

that this is packet data.
