Dear Friend

If you so in a hurry you should search the forum first... this question has been asked before :)

Anyway C++ on which operating system? the only thing you need is to be able to talk to the serial port and this is done slightly differently depending on the operating system

for example typing "c++ serial windows" into google leads to this -> http://www.codeproject.com/system/serial.asp

if you need linux or mac just type the right word into google
