CD comes FROM the modem... but an AT&C0 issued to the modem (or most
modem's default) will keep it high.

The ports/modems/lines I saw this on occasionally worked perfectly 99% of
the time. Just one instance every 8 or 10 months would popup. I think is
was on PPI V.24 modems. Since it was so rare, I think it was either some
kind of screwup between the telcon and the modem or just a case of the
modem losing its mind entirely (the PPIs did that a lot in earlier ROM
versions).

Anyway, it's not a problem for us since these modems are really only used
as temporary standins on rare occasions anymore.

Later.
