C Declaration Method
typedef struct
Fields
cb Length, in bytes, of this data structure.
10 Only valid value.
fsMask State mask.
The system state altered by this call. If bits 0 and 1 are off,
the echo state of the system is not altered. If bits 2 and 3 are
off, the binary and ASCII state of the system is not altered. If
bits 0 and 1 are on, or if bits 2 and 3 are on, the function
returns an error. If binary mode is set, echo is ignored.
Bits 15-9 Reserved.
Bit 8 Shift return is on.
Bit 7 Length of the turn-around character (meaningful only
if bit 6 is on).
Bit 6 Turn-around character is modified.
Bit 5 Interim character flags are modified.
Bit 4 Shift state is modified.
Bit 3 ASCII mode is on.
Bit 2 Binary mode is on.
Bit 1 Echo off.
Bit 0 Echo on.
chTurnAround Turnaround character.
Definition of the turn-around character. In ASCII and extended
ASCII format, the turn-around character is defined as the
carriage return. In ASCII format only, the turn-around character
is defined in the low-order byte.
fsInterim Interim character state and NLS shift state.
Bits 15-8 NLS shift state.
The meaning of the NLS shift varies by language. The
following bits are defined to access this data:
NLSS_NLS1 (0x01) - Fullwidth, National layer
NLSS_NLS2 (0x02) - Katakana, JAMO phonetic
NLSS_NLS3 (0x04) - Hiragana, Hangeul, TsangJye
NLSS_APPL (0x10) - Application bit
NLSS_NLS4 (0x40) - Romanji, HanjaCsr
NLSS_KANJI (0x80) - Kanji, Hanji
Bit 7 Interim character flag is on.
Bit 6 Reserved.
Bit 5 Application requested immediate conversion.
Bits 4-0 Reserved.
fsState Current shift state.

Bit 14 CapsLock key down.
Bit 13 NumLock key down.
Bit 12 ScrollLock key down.
Bit 11 Right Alt key down.
Bit 10 Right Ctrl key down.
Bit 9 Left Alt key down.
Bit 8 Left Ctrl key down.
Bit 7 Insert on.
Bit 6 CapsLock on.
Bit 5 NumLock on.
Bit 4 ScrollLock on.
Bit 3 Either Alt key down.
