[pe.cust.general] doing time, losing time

    lsuc!dave asked about his P-E running slow.  Indeed it is
because of missing some clock interrupts.  On the P-E under 
Edition 7, all hardware interrupts have basically the same
priority.  This will presumedly be changed (fixed?) in Xelos.

    Our solution was to buy a $189 Hayes Chronograph and put it
on the other RS-232 line coming from the 2-line commux that runs
the console.  (If your machine is configured anything like ours,
that other line is basically useless because it's impossible to
get to, anyway)  And have /etc/rc read the clock when the machine
boots.  Take heed, I wouldn't put it into the crontab to reset 
itself automagically, because /etc/cron could get confused and
start some things twice, or not at all, especially if the clock is
very far out.

       I'm not in Dallas this week, so I've got to do something,

That's curious. How is it hard to get to? We use the 2nd line for
a printer (yeah, RS-232 connection, but it's good enough for us).
We have 34 ports on our 3220, and the 2 lines for the console & printer
and just as accessible on the other 32.
