This function returns the maximum number of bytes that the hardware buffer can hold, not counting the padding, stop, and start bits.
ULONG HWGetRxBufferSize( PVOID pContext );
Parameters
Return Values
Returns the number of bytes in the hardware receive queue.
Remarks
This function supports the implementation of the PDDs of serial port drivers. The serial port driver's MDD layer ensures that the RX holding buffer is large enough to store at least one full HW Buffer worth of data, and provides additional room required to allow flow control.
