https://bugs.winehq.org/show_bug.cgi?id=47364

Bug ID: 47364
           Summary: COM ports do not work
           Product: Wine
           Version: 4.9
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wineserver
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Created attachment 64703
  --> https://bugs.winehq.org/attachment.cgi?id=64703
program run with com debugging.

Regression:  Since the last update on Fedora 29 to wine 4.9 the com ports no
longer work.  I have the registry entry for ttyUSB2 linked and it stopped
working after the last update.  The program is PUTTY.EXE but other programs
also do not work such as winlink-express.  The message from putty is "end of
file reading from serial device"

Can you do a regression test to find out which commit broke it?

How do you know "wineserver" is to blame here?

I know it worked fine in wine 4.8 but not much more than that.  I am not sure
if the problem is wineserver as I don't really know where the com port code is.

I can try and go back to wine4.8?  I don't really build wine from source so not
sure how to do that level of regression.  I could try to build a newer version
if there is one?

Well, the most useful would be a regression test. When it's between 4.8 and 4.9
only that would help. Or instructions on how to reproduce the bug.

to reproduce the problem download putty from the internet and run via wine
putty
configure a serial port and try to open the connection.

UPdate:
I built the latest GIT build wine-4.10-154-gc674ceefe1 and it appears to be
working now.

I am not sure how to do the regression testing to see which patch caused the
problem. I have not decide if I want to install this build or just wait til the
next update from fedora repo.

When it works now, there's no need for a regression test, I'd just wait for the
next build (and maybe in the meantime downgrade).
