c application for parallel communication with direct memory access
I'm having a problem with a parallel connection I've got to establish
using DMA (Direct Acces Memory). I've got to write some characters to a
parallel port with a given address, through a C application. I know that
for a PIO acess, there are the _inp/_outp functions, but I don't know how
to manage a direct memory acces parallel communication. Does anyone know
how I should do or has any good links (I couldn't find any even after long
research on the Web :s ...) Thank you in advance
