Care to share the test configuration with us?  I use SLIP over a Microcom
AX/9624c MNP Class 6 modem and a cisco terminal server.  I see the modem
lights grinding away, waiting..., grinding away, waiting..., etc.
It's almost as though the VJ algorithms were throttling...  I found I could
get more files through by starting 2-3 FTPs so that one is still running when
the other 1-2 are stalled.  Sort of round-robin FTP transfers; doesn't work
if I've only got one file to transfer though... :^(

When you're FTPing and your only link is tied up, you're quite happy to be
able to get *any* response to keep working.  If only I had what ammounts to
"local echo" or tn3270-type buffering on telnet over SLIP... sigh.
