Configure your terminal (Hyperterminal, minicom, other) with the following settings (these may differ by modem):

To make sure your connection works, issue ATZ to the modem to use the default configuration.  Note: most modems are case insensitive, but don't push your luck with mixed cases.

The resulting OK indicates that you have sucessfully connected to your modem.

Now, enable caller ID.

AT+VCID=1 OK

If there isn't an OK, but an ERROR, your modem either doesn't support caller ID or it uses a different command to enable it.  Here are some other common commands:

• AT#CID=1
• AT%CCID=1
• AT%CCID=2
• AT#CID=2
• AT#CC1
• AT*ID1

Caller ID is enabled now.  When you have an incoming call, you should see something like this:

RING   DATE = 0627 TIME = 1305 NMBR = 9999999999 NAME = JOHN DOE   RING

If you see something like this, your modem and phone line support caller ID.
