A quick and dirty version might be to put the fd (s?) in a global variable, 
create the process and guard all access to the file descriptor(s?) in both 
processes with BeginCriticalSection() and EndCriticalSection(). 

I once wrote a serial communication library with one instance of a C++ 
class controlling, and two processses reading or writing the ports. It 
worked quite well with the CriticalSection class guarding all access to 
the class.
