/dev/ports is the Linux way to access the parallel port directly. Another way is to use inb/outb but I think that will workn on the x86 platform only. sanei_ab306.c tries both ways and on first sight, sanei_pio does, too. I guess the most portable way is to use libieee1284, if available. See sanei_pa4s2 for an example. Bye, Henning
