Thanks for your help

Never heard of SetCommPort but the majority of the others (SetCommState, SetCommMask, CreateFile etc.) are declared in winbase.h.

The function you were looking for was SetupComm. You should use it with something like this:

...
HANDLE handle = CreateFile("COM1", GENERIC_READ|GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);

SetupComm(handle, 2048, 2048);
if (!SetCommState(handle, &DCB)){
//Handle error here
}
...

The DCB is a structure that hold the parameters for the com port: baud rate, parity, etc... You just pass a pointer to that structure to the SetCommState function.
