OK here's the deal:

Apparently whatever does the timeout thing for file IO is waaaay too 
short-tempered.

I fixed the problem by preventing the fileIO from closing on timeout - 
apparently forever, but who cares, it works.

Comment out the following lines in ./dlls/ntdll/file.c in two places:

//            wine_server_release_fd( hFile, unix_handle );
//            return STATUS_NOT_IMPLEMENTED;

and both USB-serial dongles and PCMCIA-serial cards will work.

YAAAY!
