- I've been bitten by this one on several systems.  What I've done is 
- write my own version of cat (typically 10 lines or so) that runs quite
- slowly, typically by reading 100-byte chunks, writing them, and then
- doing sleep(1).  I make a script called "cu" that has this "cat" in
- its search path before /bin, and knows the name of the real cu.  It
- seems to work pretty well.

A simular technique that I use is a C program that metes out characters with
any number of delay schemes using fflush(), sleep(), and optional characters
in the file to flag additional delays. I use this as a filter with the ~$
command. It was a quick and dirty workaround to transfer a file to an IBM
mainframe that didn't seem to like me at all, but has prooven to be of enough
utility to keep around.
