We've discovered one minor hitch of the switch to the Emulex.  The DH
manipulates modem-control lines in rather more complex ways than the
DZ, and the Gandalf modem on the CSRG line is set in such a way that
this matters.  (Specifically, it is paying attention to RTS, which
just tracks DTR on a DZ but is separately controllable on a DH; the
standard DH driver holds RTS at 0.)  The CSRG line is on a DZ line
until this can be cleared up; I haven't quite decided whether it is
better to fiddle with the modem's option settings or make the driver
a bit more sophisticated.  None of the other Gandalfs are affected.
