I have my Microport system polling a HP-9000/500 on port tty0.  Port tty1
is unused, uucico and a shell are the only processes running.  At 9600 baud,
the system crashes with a "Double panic: tss fault" after about 10 minutes
into the file transfer (consistently).  I tried both the standard kernel and
the "large" kernel with versions 2.2.2L and 2.2.2U with the same results.
The problem has not (yet) occurred at lower baud rates.
