I'm working with this code[1] to connect to a virtio virtual serial port
in a Windows VM running in QEMU. When the program first starts up, it
has no problem dialing the serial port (at path), and I can stop and
restart the program without issue. However, if I try to close then dial
the serial port again, I get a Windows "Access denied" error returned by
the dialSerial function.
Is there any way to fully release the file handle so I can reconnect to it without having to restart the application? I'm needing to do this when I detect a disconnect on the other end so communications can be re-established.
