 I actually liked the 'modemcap' file that came with the Convergent Tech
miniframe. The things it was missing (in decreasing importance) were:
 1) The ability to flush the input buffer.
 2) The ability to branch Backwards (with a loop limit counter)
 3) The ability to change baud rate.
 4) The ability to change the timeout interval.
 5) Branching labels.

   With all of those abilities, it would have been GREAT, since, it could then
handle almost ANY modem.
