Unfortunately I couldn't find the vendor's refrence manuals. All
I could find where pointers to this:
http://www.wch-ic.com/download/list.asp?id=126
but that link is dead. If someone has a copy of the reference sheet /
programmers guide for this I would greatly appreciate it sent my way.
Testing:
-verified minicom can communicate a various speeds using each RS-232 port
through a NULL modem cable.
-grub serial doesn't seem to work, but I didn't really dig into it.
-kernel boot console works, which is the only thing I was after.
-Link to the one I used: http://www.iocrest.com/en/product_details276.html
