Apologies...wasn't sure how you were using ncurses. Had to throw out the 'corner case'

My bad...should have directed you up a few more lines.
If you look up at line 9341 in 'configure' (in the ncurses directory) you will see a reference to..
--enable-sp-funcs or --disable-sp-funcs
This also will cause NCURSES_SP_FUNS to be enabled/disabled.

To see all the available options with a build, you can either type
./configure --help | more      <-- pipe the output
- or -
./configure --help >> somefile.txt <-- my prefered option as then I can look at all the available options in a text editor

If this isn't the case then I may have to defer to the 'gurus' on this one.

Good Luck.

a) is unlikely because the terminal is Gnome Terminal.
b) i do not see a configure option with_sp_funcs (or anything like it)
and when i look at the symbol table i do see echo and noecho.

Two schools of thought....
a) hardware
b) software

For a) assuming some kind of external comms - do you have some form of loop back? I'm going to say this is probably unlikely and would be special case. However, I have to throw it out.

For b) when you did you initial build (assuming you built from source) did you config using the flag "with_sp_funcs"? From the source see the configure file (line 9350 sets the flag NCURSES_SP_FUNCS) and lib_echo.c (NCURSES_SP_FUNCS is used to enable the build of the noecho function at line 77).

does anyone know what might cause characters to be echoed to the screen
even though noecho() was called at startup?
