I'm confused. IIRC, the command was four characters, either
> ATDT or ATDP. Are you saying it would work with three?
Yes. With ATD, it would default to rotor dialing.

That's what the comma did. But actually in most electronic PBXs, the pause wasn't really necessary.
Way back then a lot of people still had rotary service and most

I don't agree. When the Smartmodem came out, touch tone was greatly in the majority and really was a better choice for lines that did both.
IIRC, Hayes was the leader in modems, but didn't they end up going

I *do* understand it. They were a bit pigheaded about their pricing. I believe that that is what did them in. They thought people would pay four hundred for a Hayes modem (versus seventy-five for a Hayes-compatible (non-Hayes) modem). In other words, they thought people would continue to pay the big money to drive a Cadillac. I believe it did them in.
It made me very sad, too. I believed in Hayes quality. When I was at SkyTel, we used a bunch of them for our field equipment and on our PCs at the office to call up that equipment.

I'm sure it did. But all you can do in most cases is to take their word. After all, they are the customer.
That certainly does happen. But more commonly is people who _think_

I know it's common. But it's something you have to live with.
