There is actually a lot of code that is different between rz/sz and
zmtx and zmrx; this is evident from the fact that rz/sz work really
well, and zmtx and zmrx don't work at all, at least when I tried them
on AIX.
It should be noted that zmodem was developed by Mr. Forsberg, and the
sale of his implementation of the protocol is a primary source of his
income. He is not Bill Gates -- if you call Omen Technologies, you
will either get him or his wife. Considering the daily, constant,
commercial use of his products, it would behoove companies in the
internet community to shell out a few bucks to him for his efforts.
I am a satisfied customer of Mr. Forsberg (for over 10 years!), and have
no other connection to him.
