After some searching, it's been decided that the thread should
not use WaitCommEvent but I can use WaitForSingleObjectEx. I
wasn't there for that one so what ever. I just want a test bed
for testing the thread and it escapes me.

What I'm trying to do now is open the port twice - once for
reading and another for writing but on the second call to
CreateFile, I get an Access denied error:

    WCom = ::CreateFile( TEXT("COM1"), 
                         GENERIC_WRITE,
                         FILE_SHARE_READ,
                         NULL, 
                         OPEN_EXISTING,
                         0,
                         NULL
                       );


    RCom = ::CreateFile( TEXT("COM1"),
                         GENERIC_READ,
                         0,
                         NULL,
                         OPEN_EXISTING,
                         0,
                         NULL
                       );

Please note that I've tried what seems to me to be all logical
combinations of the dwDesiredAccess and dwShareMode.
