The "Hayes" command set was developed by Bizcomp, Corp., and then bought
by Hayes.  Anyway, Hayes is the legal owner of it, now.  Companies who
wish to use the Hayes command set must sign a pricey license with Hayes.

One of the suits that went to court was the manufacturer U.S. Robotics,
who felt that the license fee (and even the idea of it) was too much.
They lost and now are paying Hayes like everyone else.

It doesn't.  And Hayes owns the AT command set.
