Low level buffering is great but it is still a performance pig.  If you
can get one interrupt per packet then you can support more interfaces in one
machine.  I was thinking of a couple of SLIP lines a ethernet, token ring
and makybe an arcnet.  This thing becomes interrupt intensive unless you can get
rid of some of the serial interrupts.

It's really bad if your running 9600/19200.
