I've been having some problems with SLIP over /dev/com1 lately.

For the most part it works fine, but every once in a while, it
will get "stuck."  No more information will flow from my
machine over the SLIP connection, and vice versa.  The only way
to get it going again is to kill the slattach process, wait
for any buffers to be flushed, and then restart the slattach
process.

Weird?  This tends to happen usually when a lot of information
is being sent at once.  Overflowing buffers, possibly?

I've tried using the original com.c driver and the bi-directional
one by Chris (using /dev/ttyd1).  Neither has solved the problem.
