Assuming that you have rw permission on tty04 (and you should get a
reasonable error message if not), the most likely problem is that you
are placing the call with cu and using its shell escape to start rz.
The problem is that cu runs as 2 processes. One reads the keyboard
and writes to the tty, the other reads the tty and writes to your line.
During the shell escape the process reading the tty is still active.
Without source to cu it probably can't be fixed.  If you can get a
copy of kermit you can use it to place the call, then run rz/sz in
a shell escape.
