Do the two tricks I described.
Everything should work, "but" :
Unfortunately, most likely due to a bug, the software does not receive data over the serial adapter, it can only send. (I know that by monitoring activity using "ttylog")
- most likely due to a bug, as other programs would work just fine.
The Only thing this application needs to get my $100 pledge, and gold medal, is fixed serial interface.
(I have another program with the same problem (one way communication) - so I am sure it's a WINE problem)
