Members

dwComPort

Indicates the number of the COM port to use. The value for this member can be 1, 2, 3, or 4.

dwBaudRate

Indicates the baud of the COM port. The value for this member can be one of the following:

CBR_110 CBR_300 CBR_600
CBR_1200 CBR_2400 CBR_4800
CBR_9600 CBR_14400 CBR_19200
CBR_38400 CBR_56000 CBR_57600
CBR_115200 CBR_128000 CBR_256000

dwStopBits

Indicates the number of stop bits. The value for this member can be ONESTOPBIT, ONE5STOPBITS, or TWOSTOPBITS.

dwParity

Indicates the parity used on the COM port. The value for this member can be NOPARITY, ODDPARITY, EVENPARITY, or MARKPARITY.

dwFlowControl

Indicates the method of flow control used on the COM port. The following values can be used for this member:

DPCPA_DTRFLOW

Indicates hardware flow control with DTR.

DPCPA_NOFLOW

Indicates no flow control.

DPCPA_RTSDTRFLOW

Indicates hardware flow control with RTS and DTR.

DPCPA_RTSFLOW

Indicates hardware flow control with RTS.

DPCPA_XONXOFFFLOW

Indicates software flow control (xon/xoff).

Remarks

The constants that define baud, stop bits, and parity are defined in Winbase.h.
