If your modem suypports CLI (Calling Line Identification) simply turn this feature on using the appropriate AT command for your modem (usually at+CLIP but see your manual).

Your modem will then send a string out the serial port whenever it receives CLI data, your VB app just needs to read the serial port for these messages.

Of course if your modem does not support CLI you'll need to get one that does :)

See this FAQ:
http://bbb.darktech.org/~phriik/text/CID/cli_faq.html

Search it for the following text regards your Modem:
"I have seen a review that suggested that Aztech 56K modems support 'CLI', but this was refuted by their head office"

The FAQ may still be usefull to you if you have another modem.

Please give precise details of your modem as this FAQ is old, but we do not know the age of your modem - things may have changed since.

HTH - Peace
