Hi all, I'm using gcc for the H8/3048, and am using the standard C language libraries, and newlib. To use scanf(), printf() etc, files need to be defined for stdin and stdout. Somehow, these have to be connected to the input and output of the rs232 serial port. What's the usual way of doing this? I currently have an array that gets filled by received characters (interrupt driven), and an output array that gets its contents emptied out the serial port when a function triggers the tx interrupt. After the array empties, the tx interrupt is disabled. -- ******************************************* * Russell Shaw, B.Eng, M.Eng(Research) * * email: russell@webaxs.net * * Australia * *******************************************
