Actually, this is pretty stupid.  It is a legal thing, not a technical
thing.  When the phone company (was only one back then) first
introduced tone dialing, it was a "feature", and so it cost extra.
Nowdays, the whole phone system operates with tone dialing, but
because it was tarriffed back in the early 60's as an extra cost item,
it is still an extra cost item, so some people say, "Why do I need to
pay extra for that?", so they refuse to pay the extra couple of
dollars per month for tone dialing.  This actually costs the phone
company extra to handle pulse dial now because they have to convert it
to tone to feed it into the rest of the network.  They used to have to
convert the tones into pulse.  :-(

I recently had another line installed and I forgot to request tone
dialing, so of course, I got pulse.  At first I thught my nice new
Zyxel modem arrived broken out of the box, but then I figgured it
out.
