I'll just follow this with a copy of the program in question.  It has 
enough internal documentation to guide its user; I think 8500 words
on this rather trivial subject is overkill.

The program uses the little-known and little-used block transfer 
mode of PIP which uses XON/XOFF to control transmission.  While this
is a rudimentary and slow way to handle transmission of binary
data, it is good enough to bootstrap modem7 or some such program.

Try it; you'll like it.  It is simple and small, but bigger and
more verbose is not necessarily better.
