Contains information about the configuration of the COM port.
Indicates the number of the COM port to use. The value for this member can be 1, 2, 3, or 4.
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 |
Indicates the number of stop bits. The value for this member can be ONESTOPBIT, ONE5STOPBITS, or TWOSTOPBITS.
Indicates the parity used on the COM port. The value for this member can be NOPARITY, ODDPARITY, EVENPARITY, or MARKPARITY.
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).
The constants that define baud, stop bits, and parity are defined in Winbase.h.
