   If you have one of the later coreboards (8342- I think, but don't quote me),
you'd be better off installing an 8530 and using that. This gets you two
hardware serial ports and, even though the 8530 is a real bitch to program,
it's lots better than the software UART. Don't know about QTERM, but there's
a ZMP overlay for this configuration.
