Hey skbandi,

The Microsoft modem control does not support this feature directly, that is to say caller ID is supported by a special command sent to your modem, thus caller ID depends on your modem rather than on the ms modem control.

first check to see if your modem support caller ID then

you can use these command to send to your modem using the MScomm control.

If your modem's hardware supports Caller ID, use the V.253 standard command AT+VCID=n command, where
n=0 disables Caller ID
n=1 enables formatted display
n=2 enables unformatted display

Good Luck ;-)

Hi CycLonE,
i tried it but failed. can u tell me the sequence of operation. suppose my appication is waiting for a call with the portopen method. then if a call comes, it fires a oncomm event and recieves RING from the modem, but the caller Id info is passed between the 1st and the 2nd rings by the telecom company. so how can i catch that? if u can provode me with some logic and code, i really appreciate it. coz the msdn help abt the mscomm control is not sufficient, neither the modem manual with its list of AT commands.
my modem has callerid feature.

Sure it's a very simple process:

To send commands to the modem using the MSCOMM control:
say mscomm name is "MSComm1"
- "AT" is used before any command.
- the Chr$(13) or return is used after each command.
- the command line would be:
MSComm1.Output = "ATVCID=n" & Chr$(13), where :

n=0 disables Caller ID
n=1 enables formatted display
n=2 enables unformatted display
