I'm confused. IIRC, the command was four characters, either
ATDT or ATDP. Are you saying it would work with three?

Also, for dialing out of a PBX, wasn't a 'pause' character needed to
allow time for the second dial tone?

Way back then a lot of people still had rotary service and most
systems supported both. I don't think early on defaulting to pulse
was such a bad idea for those days.

IIRC, Hayes was the leader in modems, but didn't they end up going
bankrupt? I didn't understand that.

That certainly does happen. But more commonly is people who _think_
they did something when they actually didn't, or for some reason what
they entered didn't take (ie keyboard locked up and they didn't
realize it -- that's very common.)
