First a big thanks to Charles Hannum who's really improved
com.c lately.  But... (there's alway a but, isn't there?)

I still have silo overflow problems.  I've got a laptop
(with a 33MHz 486) so I'm stuck with UARTs I've got and
they are 16450 compatible.

With the old driver I couldn't run SLIP at all (I use
38400 between the computer and the modem).  With the new
driver it works, but I get roughly one "silo overflow"
per second.  That is, it works as long as there is no other
activity on the machine.  As soon as I start using the disk
the are too many silo overflow and SLIP just stops (it
usually picks up again a while after disk activity stops).

Even when it works the overflows I get reduces the capacity
with about 25%.

I guess this means I'll have to dust off my really ugly patch
to com.c and install it again. *sigh*

PS.  On the positive side: wd.c seems to work better now!
