: That's utterly bizzare that async IO isn't working on the serial lines, I seem
: to recall using it way back a million years ago.

TIA runs on 2.0R w/o any problems.  It would have big problems if
async I/O was broken for serial lines....

Don't know what the deal is, but TIA just does a fcntl of the fd with
the O_NONBLOCK bit set after reading the flags on fd 0.
