I have not completely understood the difference between this two functions (waitingdata/waitingdataex). In my understanding, the waitingdata function gives the number of bytes that are in the OS buffer, while waitingdataex gives the sum of bytes in the OS buffer + bytes in the HW buffer? Has anyone an advice in which case to use which function?
And a second question if I may: For the Recv. functions there is a timeout, example a:=RecvByte(50) What happens during thin 50ms timeout? When a byte is received during this 50ms, will it be contained in the function result? Or is it only the timeout for the transfer of what is already in the OS buffer to the function? Thank you, Chris
