Hi, all.

My embedded board have paralled port with 25 pin. ( IO port 0x387, and SPP
mode )
I'd like to access and use it from linux...

I think I need linux parallel port device driver to access ....
I'm new to parallel port .... so If I get some simple code about how to
send a char or string...
It will give great help to me....where can I see it to learn parallel port?


(how parallel port initialize and send a char , and closing.... )


Thanks.. have a nice day.

modprobe parport_pc (assuming this thing is an x86, if not, you
should've said something)
modprobe lp
