How to create a Serial port communication mex file in C++ to use in MATLAB?

Dear all,

I am looking for using mex file written in VS C++ for serial port communication to make it fast in MATLAB.

I want to know how to write a relevant C++ code for serial port read/write and make a mex file and how can I access in MATLAB to read and write the data.

If anyone knows this let me know.

Cheers.
