Pulse dialing and 3.5.1.4

[Chris Lewis]

People may remember some time ago my remarks about my machine
crashing during pulse dialing if any significant amount of
disk activity occured.  As often as 2 or 3 times a day.
Averaging several times per week.

Well, during two months of tone dialing, my system has crashed
precisely once, and that due to a static hit.  So, if people
are encountering mysterious crashes, they're running
a relatively old OS release (3.5.1.4 is what I've got), and
they're pulse dialing, switching to tone dial does the trick.

(Yeah, maybe one day I'll upgrade to 3.51m where this is fixed,
but 3.5.1.4 works just fine for me.  Switching to tone dial
cost less than buying the floppies I'd need to redo this thing)
