A wild guess is that you are hitting a usb driver bug, I had several issues
with usb-serial converters in linux.

If you don't check the return of "ioctl(fd, TIOCMGET, &serial)" you are simply
hiding the issue, the serial variable will not be filled with the data
requested.

You could try playing with strace to check if the problem is really in a write
call in the lower library levels or if it gets in a loop inside wine.
