sounds right to me :)

Ahhh that sounds nice doesn't it?until very recently I had a very "nice"
problem...
My web page is on delphi and until recently they did no tallow
ftp at all...
being an old VAX system which has been operating since the mid-early 80s
and really until recently hasn't chenged terribly much in allot of ways...
even through telnet...I could only at best zmodem the files (tho
kermit and xmodem were also availble for the true masochists)

CRT = Combined Rlogin and Telnet ...great little progam works like a charmBefore
I got rid of windows completely I used it all the time
check out www.vandyke.com
one of the few Windows programs I can actually say was very well done
I have heard of someone hacking their telnet  bit so that it would allow them
to suspend it and then pipe its output to a command (ie rz) or vica versa
IMHO it is a GREAT IDEA...
I may look at the source and hack that one up myself (yea I could just look for
the patch
but...not as much fun..besdies...sounds liek an easy one)
for such a simple and usefll little feature...im surprized it doesn't come
standard as
a part of telnet
