I think the bug that I'm introducing (continuing to use serial
output/ignoring the value of stdout) is much better than a hard lockup
(the current bug), but I definitely see your point.  I'm not a user of
the logbuff or LCDs, etc at this point in time, so feel free to do what
you'd like with the patch.

Best,
Peter
