set-input-modeinterrupt flow meta &optional quit-char
This function sets the mode for reading keyboard input. If
interrupt is non-
nil, then Emacs uses input interrupts.
If it is
nil, then it uses CBREAK mode. The default
setting is system-dependent. Some systems always use CBREAK mode
regardless of what is specified.
When Emacs communicates directly with X, it ignores this argument and uses interrupts if that is the way it knows how to communicate.
If flow is non-
nil, then Emacs uses XON/XOFF
(C-q, C-s) flow control for output to the terminal. This
has no effect except in CBREAK mode.
The argument meta controls support for input character codes
above 127. If meta is t, Emacs converts characters with
the 8th bit set into Meta characters. If meta is
Emacs disregards the 8th bit; this is necessary when the terminal uses
it as a parity bit. If meta is neither t nor
Emacs uses all 8 bits of input unchanged. This is good for terminals
that use 8-bit character sets.
If quit-char is non-
nil, it specifies the character to
use for quitting. Normally this character is C-g.
current-input-mode function returns the input mode settings
Emacs is currently using.
This function returns the current mode for reading keyboard input. It
returns a list, corresponding to the arguments of

nil when Emacs is using interrupt-driven input. If
nil, Emacs is using CBREAK mode.

flow control for output to the terminal. This value is meaningful only

the meta bit;
nil means Emacs clears the eighth bit of every
input character; any other value means Emacs uses all eight bits as the
basic character code.
