1069 Return information about the way Emacs currently reads keyboard input.
|
|
|
1070 Optional arg CONSOLE specifies console to return information about; nil means
|
|
|
1071 the selected console.
|
|
|
1072 The value is a list of the form (nil FLOW META QUIT), where
|
|
|
1073 FLOW is non-nil if Emacs uses ^S/^Q flow control for output to the
|
|
|
1074 terminal; this does not apply if Emacs uses interrupt-driven input.
|
|
|
1075 META is t if accepting 8-bit input with 8th bit as Meta flag.
|
|
|
1076 META nil means ignoring the top bit, on the assumption it is parity.
|
|
|
1077 META is neither t nor nil if accepting 8-bit input and using
|
|
|
1078 all 8 bits as the character code.
|
|
|
1079 QUIT is the character Emacs currently uses to quit.
|
|
|
1080 FLOW, and META are only meaningful for TTY consoles.
|
|
|
1081 The elements of this list correspond to the arguments of
|

1082 `set-input-mode'.
