@param BaudRate The requested baud rate. A BaudRate value of 0 will use the the

device's default interface speed.
|
|
@param Parity The type of parity to use on this serial device. A Parity value of

DefaultParity will use the device's default parity value.

@param DataBits The number of data bits to use on the serial device. A DataBits

vaule of 0 will use the device's default data bit setting.
|
|
@param StopBits The number of stop bits to use on this serial device. A StopBits

value of DefaultStopBits will use the device's default number of

stop bits.

@retval EFI_SUCCESS The device was configured.
