I (and a couple of other sites with these modems on loan) are planning
to conduct some experiments.  It is very clear that conventional file
transfer programs will not function properly "as-is" with a half
duplex modem that "simulates" full duplex in this manner.  There are
also some issues regarding transparency.  To operate at high speeds,
the modem requires ^S^Q flow control to operate in a particular manner
to/from the hosts, or to have full RTS/CTS functions built into the
drivers.  As has been reported previously, the modem is basically
unusable for most interactive applications.  True throughput over
typical dialup lines has also yet to be determined.  Large block sizes
on suboptimal circuits could potentially result in massive amounts of
time being spent on retries--this is one of the reasons that
"smallish" block sizes are usually preferable on dialup circuits, but
this modem won't function very well with smallish blocks.

One problem that has been reported is that the modems may crash on
power glitches and require manually power cycling to recover.  Also,
right now the modem does not do automatic speed hunting for command
input, though that is promised in a future firmware release.

More details later.  Experiments are really only getting
under way.
