Re: Character at a time input (was Re: Where is less source?)

Scott,

I'm afraid to do that on Windows you'll have to reboot after reading each 
character.


OK. Not to be totally frivolous: Yes, "cbreak" and "raw" modes work under 
Cygwin. You can see it work from the command line:

% stty cbreak
% cat
tthhiiss  iiss  aa  tteesstt

%

Just to be clear, I typed "this is a test<RETURN>". For reasons I don't 
understand, CTRL-D (which I verified is my tty's eof character) did not 
generate a end-of-file condition--I had to use CTRL-C to terminate the 
"cat" command. What seems even stranger is that "raw" mode behaved the same 
way. I suppose those symptoms occur because I don't include the "tty" 
option in $CYGWIN.
