Yeah, they seem to be similar, as I've almost got in-kernel driver to
work by looking at lspci output and making wild guesses, but then trying
to use /dev/ttyMI3 hang my PC.

I now compiled the driver provided by moxa and it works, so I now have a
code to refer to, and it has special-case for port 3 ;-) Unfortunately
their driver only supports kernels up to 2.6.30, so it will take
additional efforts to run it on recent.

I'm going to try to make in-kernel mxser to work with this board, --
will see how it goes.
