--- Comment #13 from Roger <rogerx.oss at gmail.com> ---
I'm able to read through the serial to USB convertor using the mct_u232 driver.

While reading, wine spawned the following error:
fixme:comm:set_queue_size insize 4096 outsize 4096 unimplemented stub

After apparently stopping the assigned task, wine spawned the following error:
err:comm:stop_waiting failed to clear waiting state: 0xc0000008

Unknown if the two errors caused any problems with the data transfer, but
guessing the first error was probably treated as a notice or there's a fall
back for the device.  The second error would have to check the data transferred
for any problems.

Apparently, the device treated both as notices and the application apparently
functioned as it would have under MS Windows.  (Bugs and all.  Could be those
errors were spawned by the original MS Windows application binary for all I
know.)

I have not tried writing to the device through the serial USB converter, due to
migrating to another application for maintaining the device.

If you can write through the serial USB converter, probably a safe bet to close
this bug.
