by Who can tell me the difference of Windows 2000's DCB structure from
Windows 98's
I Know It is :
typedef struct _DCB { // dcb
DWORD DCBlength; // sizeof(DCB)
DWORD BaudRate; // current baud rate
DWORD fBinary: 1; // binary mode, EOF ?| ??????? ??
DWORD fParity: 1; // enable parity checking
DWORD fOutxCtsFlow:1; // CTS output flow control
DWORD fOutxDsrFlow:1; // DSR output flow control
DWORD fDtrControl:2; // DTR flow control type
DWORD fDsrSensitivity:1; // DSR sensitivity
DWORD fTXContinueOnXoff:1; // XOFF continues Tx
DWORD fOutX: 1; // XON/XOFF out flow control
DWORD fInX: 1; // XON/XOFF in flow control
DWORD fErrorChar: 1; // enable error replacement
DWORD fNull: 1; // enable null stripping
DWORD fRtsControl:2; // RTS flow control
DWORD fAbortOnError:1; // abort reads/writes on error
DWORD fDummy2:17; // reserved
WORD wReserved; // not currently used
WORD XonLim; // transmit XON threshold
WORD XoffLim; // transmit XOFF threshold
BYTE ByteSize; // number of bits/byte, 4-8
BYTE Parity; // 0-4=no,odd,even,mark,space
BYTE StopBits; // 0,1,2 = 1, 1.5, 2
char XonChar; // Tx and Rx XON character
char XoffChar; // Tx and Rx XOFF character
char ErrorChar; // error replacement character
char EofChar; // end of input character
char EvtChar; // received event character
WORD wReserved1; // reserved; do not use
