Re: [Xen-users] Serial port in domU/0

Just to close this up.
Instead of trying to hack the xen code, I decided to buy a USB-RS232 cable.
And by passing the USB port to the domU, I was able to access the serial
However, this required abit of kernel compiling, as usbserial driver was not
compiled into the kernel, and obviously the driver for converted need to be
compiled too.
And it all works well.
