    With respect to GPIO control, tt depends on what version of Linux you are running. Early versions use devfs and ioctl. Later versions use sysfs and read/write. If you have the Linux kernel source, the "Documentation/gpio.txt" describes the capability of your version. Note that your kernel must be compiled with GPIO device support.
