Use the Connection Manager, as it is for general connections. TAPI is a set of instructions that essentially allow a connection between two cell phones using the same programs, i.e. if you wanted to send a picture or something to another cell phone running the exact same picture/editing software.
thank you very much for your concern,
i am planning to make data call (using the CSD channel)
so there will be the same program on both mobiles (the calling and the receiving one)
the program will also be a real time program.
will you still advise me to use connectionManager instead of TAPI?
PLEASE REPLY AS SOON AS POSSIBLE
waiting your response
thank you in advance
