Need Help with sz/rz

[Mike Johnston]

I have been trying to use sz/rz on my machine now for about two weeks
with no luck. I compiled it with no problems whatsoever. The problem is this:

I have transfered sz to a remote machine and I wish  to use it for file
transfers. I dial into the remote system and say:

sz foobar

The remote prepares for transmission. Now, if I exit to the shell on my 
machine, how do I get rz to recognize that my modem port is different from 
the one I am working on? My modem is on tty04 and lets say for argument sake
that I am on tty09. I thought that something like the following would work:

rz < /dev/tty04 > /dev/tty04

But, it doesn't. Am I missing something? I suspect it is something simple
but for the life of me I can't figure it out. Can anyone help with such a
simple problem?
