A pointer to the
SERIAL_IO_INTERFACE
SERIAL_IO_INTERFACE
The requested baud rate. A
device's default interface speed.
The requested depth of the FIFO on the receive side of the serial
interface. A
ReceiveFifoDepth
device's default FIFO depth.
The requested time out for a single character in microseconds.
This timeout applies to both the transmit and receive side of the
interface. A value of 0 will use the device's default
Timeout
time out value.
The type of parity to use on this serial device. A
of will use the device's default parity value.
DefaultParity
