timings... the internal timers may be more lax allowing for longer transmission 
times before erroring out...

as far as Tiny's comment about multiple telnet hops, it makes sense because 
telnet can be switched in modes so that things like zmodem will work... that 
mode switch isn't transmitted up the line to the next telnet package because 
the first one ate it when it reacted to it... remember, no one ever expected to 
be tunneling file transfer protocols within telnet sessions... that's why, from 
a command shell account, you always telneted and then opened a separate sz or 
rz connection for your files... they weren't done inside the telnet pipe...
