Bug ID: 39793
           Summary: Starcraft freezes when starting a Direct Cable
                    Connection game
           Product: Wine
           Version: 1.7.46
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: ntdll
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

To reproduce:
1. Add yourself to the dialout (Ubuntu) or uucp (Arch) user group.
2. Log out and log back in.
3. In Starcraft, click Multiplayer, Direct Cable Connection, Ok.

The problem is that Starcraft attempts to detect which serial port is connected
by sending a burst of data on all ports COM1 through COM8. On Linux, COM1
through COM4 default to ttyS0 through ttyS3, but even though the device files
exist, rarely do all of them correspond to actual physical devices. So,
Starcraft hangs forever waiting for the write to complete successfully.
