Finally it results that my problem was a hardware problem, the machine where I
make the linux test had a faulty serial port. I plugged a usb serial adapter
and almost everything worked out of the box. I'm really impressed with the
serial port driver codec in wine.

Now I have a problem with the olivetti printer, I think the timeout raises
before all the buffer is sent to the printer, and when the program calls
PurgeComm the buffer resets and leave the printer in the middle of the page. I
will try the tcdrain patch suggested by Cihan Altinay.

Many thanks to everybody.
