Sounds like an attempt to read or write is locking up the processor.
This will happen if you try to read an empty input register or write to a
full transmit register. Disassemble location 80286 (strange, reminds me
of a very old processor...) and see which it is. Most likely you have to
check a status register first, then do the operation only if data is
available for a read.

You probably want to put in a time out as well - if you don't get any data
after x milliseconds, figure there's no more coming.
