EKF16550_HANDFLOW
A structure that contains all the stuff needed to setup hard- and software handshake for
serial ports:
typedef struct _EKF16550_HANDFLOW
{
UINT32 ControlHandShake;
UINT32 FlowReplace;
INT32 XonLimit;
INT32 XoffLimit;
} EKF16550_HANDFLOW, *PEKF16550_HANDFLOW;
ControlHandShake:
A set of flags that defines the modem lines that are used for flow control:
EKF16550_DTR_HANDSHAKE:
Use the modem signal DTR for input flow control. The DTR line is cleared by
the controller if the receive buffer reaches the programmed high water mark.
