It does not work :( The test program freezes trying to flush the serial 
port (at
function PurgeComm). Just before that the trace says  that the cbOutQue has 6
elements (at function ClearCommError). I think the program writes on 
the serial
port, but for any reason the writing operation doesn't succeed and the writing
operation stalls trying to do the tcdrain part. The program does not 
stops with
tcflush because tcflush discards the buffers.
Perhaps is something related to the line discipline of the port, somehow the
port doesn't accept input.

I keep investigating, many thanks!
