Sending "AT" commands to a modem

[AjayK46]

Modem USR5637 external USB
Operating system Win XP

In order to get caller ID display correctly working on this modem I need to have "&F1+VCID=1" sent as the modem initialisation string. The only problem is that this command needs to be sent to the modem after every incomming call. Setting this initialisation string is fine using the Advanced properties option for the modem but it seems to only be sent once.

How do I automate this string to be sent to the modem after every incoming call?

Any help much appreciated.

Thank you
