write your e-mail and I'll send to you a component of serial communication
you should use WinAPI function:
- CreateFile() to open a port
- ReadFile/WriteFile to communicate to it

p.s. you can use standard port names as "COM1:" with CreateFile
you can get all the serial coponents you could want here:
async32 v1.49 one is one of the best ,also dcommms is good one.
they all come with examples..
