I have written a small software to show caller id using c++ and TAPI 2 library. I have used a lineInitializeEx function to initialize a modem , and lineOpen function to open a modem line, ..etc.
My question is, how can I activate a caller id on my modem? I know I must use an AT command "AT+VCID=1" which worked correctly using a putty software, but how can I send this command in my software using the TAPI library? Any function?
