Hello, After getting information on the device driver for a PCI board multi port RS232, I want to understand the device driver of an IO device driver based on the files sio.c. I don't really make a diferrence between the function outb and the function sio_setreg, and the opposite for the function inb and sio_getreg. Could you help me? Thanks Eric
