It usually involves giving the stty command for disabling a ctrl-sequence.
It's usually 'stty susp "undel"' (BSD) or 'stty swtch "^-" (SysV) to
disable ^Z, and similarly for the intr (^C) and quit (abort program w/
core dump) interrupt definitions. SysV also allows 'stty -isig' to turn
off interpretation of the control char. (usually ^C) assigned to 'intr',
which has the advantage that you just have to do an 'stty isig' to
re-enable it, instead of remembering what key you assigned to 'intr' and
re-installing the definition. Check your stty man page for exact syntax.
