If I wanted to design a new editor for circle that looks or acts like pico
or vi and use this type character mode would I go about 
turning it on? and turning line by line mode back on when I am done
with character mode? Ie: what are the exact commands to send to the telnet
client? I have been toying with the idea of putting a pico type editor 
for OLC and writing board messages and such into circlemud for a while now..
Any help would be appriciated...
