Ping, Here's a QEMU image (124 MB) of a Debian system with the tpci200 and ipoctal drivers, in case you want to try them out:
http://dl.dropbox.com/u/1667385/qemu-ipoctal.qcow2 The root password is just 'root'. The patches for QEMU are here: http://patchwork.ozlabs.org/patch/203892/ http://patchwork.ozlabs.org/patch/203896/ And you need to run it with these options: -device tpci200 -device ipoctal232,serialX=DEV where X is a channel number (from 0 to 7) and DEV a host character device (e.g. "pty").
