Very easy - there are examples on www.codeproject.com - there is no simple solution, just a series of calls to configure the serial port (speed, bits etc.) then you use OpenFile / Read / Write / Close.
This is something I do a lot in C++.

yes sir ive seen the samples on www.codeproject.com- but the functions are limited, it only explains the communication between 2, either vb6 sending data to VC++ Dll and VC++ DLL sending data to serial ports....what i needed is the interfacing of these three, vb6 to send data to VC++ compiled DLL and then the DLL process the data and send it to serial port....so all of them are involved in the process...im a newbie on VC++ and hav not tried using the language before...pls help me sir..hav a a blessed day ahead! |

Why do you want to use C++ to talk to the serial port - you can do this with VB. I don't know how - I am not a VB person - but there are many VB programs which control a serial port, you can buy commercial code to do this for about $50.
I can't help with interfacing VB to C++, only the C++ / serial port side.
