Bug ID: 58594
           Summary: Teraterm 5.4.1 /  Serial communication not functional
           Product: Wine
           Version: 10.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Tested with Wine 10.12 on Ubuntu 22.04 running on VMware.

When data is sent to serial port teraterm GUI become sluggish/unusable. 
Menu's do not work and data sent to serial port is not shown.
When data sending is stopped GUI starts to work normally and data is shown on
terminal.

Functionality is pretty much the same as in bug-58142

Tests steps:
- Connect USB-serial port to system.
- Open serial port with teraterm & set settings(baud,stop bits...) 
- Start sending data to serial port.
- Try to open menus.

Not sure is this possible to reproduce with virtual serialport(s)
