I see the same thing with ms telnet program that I just tried the other 
day. Local echo on or off or terminal type made no difference. Works 
fine with linux and cygwin telnet (which are probably the same gnu 
code). Years back, I think I noticed with tcpdump that dos telnet sent 
each chars separately in a tcp message while gnu telnet buffered the 
whole line before sending. Not sure if this has anything to do with the 
double chars displayed.
