[Qemu-devel] new feature: attach a process to emulated serial port

[Johannes Martin]

Hi,

The attached patch adds another variety of the -serial and -monitor
options. You can now use
        -serial "exec:any shell command"
to redirect the input/output of named shell command to the guest's serial
port.

For example, you could attach slirp to the guest's serial port and then
start a pppd on the serial port in the guest:
host:   qemu -serial "exec:slirp ppp"
guest:  pppd /dev/ttyS0 57600 defaultroute

This will help getting network connectivity in guests that don't like
qemu's network drivers (like OS/2).

Tested on current (2004-10-08) cvs.

        Johannes
