[Qemu-devel] Qemu 0.7.2 on Windows - Serial port communication

[Glenn Gagné]

I installed Qemu 0.7.2 on Windows 2000 Pro and I run a Windows 95 in the virtual environement of Qemu. I have an old
MS-DOS application to use who communicate on serial port... But it's not working in the virtual environement.

Qemu is able to translate serial port data in the virtual environement through the real serial port (hardware) on my PC
?

It's not working in the host or the guest?

The -serial option works fine for me with FreeDOS. I run a few DOS apps
which do serial comm. Windows should work just as well.

Hi,

It will be supported in the next release, but only on a Linux host.

Yeah, I didn't notice you are running QEMU on Windows. I guess serial port
is not redirectable under Windows and there are no current plans to.

Under Linux I use -serial to redirect to a pty. Then you can use other apps
or emulators that will talk to a pty device. The most interesting
application here is probably socat or netcat since these will let you shunt
the serial channel onto pretty much any kind of two-way channel (for example
you could connect the pty to a real serial port, or a TCP connection to an
instance of socat on another machine, etc.)

For anyone who hasn't played with socat it's really an amazing tool.
