uucp dialers for trailblazer and courier

The following shell archive contains a dialer for the Telebit
Trailblazer and one for the USR Courier. They work with the
version of uucp found on the 4.3 BSD distribution tapes. They
were written to function in an environment where I continuosly
switch between dialin and dialout modes on the same line so they
leave the modems in auto-answer mode, you may want to change this
but that is trivial to do. I hope this helps someone out there.
If you make any changes to these routines please send me a copy
as I am sure they are nowhere near perfect.
