DPCOMPORTADDRESS

Contains information about the configuration of the COM port.

typedef struct DPCOMPORTADDRESS{
    DWORD dwComPort;
    DWORD dwBaudRate;
    DWORD dwStopBits;
    DWORD dwParity;
    DWORD dwFlowControl;
} DPCOMPORTADDRESS;

typedef DPCOMPORTADDRESS FAR* LPDPCOMPORTADDRESS;

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.
