I suspect (personally) that this is a Tripos holdover...DOS likes
to work in 400 bytes at a time.  the SER: handler is written like
the other handlers, and shares the same design concept.

This is only my theory, however.

The good news is that a unbuffered SER: handler is possible
entirely in C, (call this hypothetical handler COM:) and may
be making an appearance in the future. (either on our
Software ToolKit disk, or here).  If you want one now, MetaCompCo
has their Software Toolkit available now (entirely different from
ours) which contains an AUX: device which does unbuffered serial.
