[Xen-users] Serial port pass-through or redirect



Hi,

I tried to pass-through ttyS1 (COM2) to domU but never succeeded.
My config file:
irq=[3]
ioports=['2f8-2ff']
I can see my domU detect ttyS1 but still cannot drive it. (I can open
/dev/ttyS1 but cannot setup its baudrate).

If I unbind COM2 from 8250 driver in dom0 then my domU cannot detect
any ttyS*, it is weird.

I also tried:
serial=['pty','/dev/ttyS1']
but didn't work either.

It is difficult to let my domU to controll ttyS1 (COM2).

Thanks,
Eric
