Issue with RHEL6 with parallel port communication?


I was trying out the parallel port communication on RHEL 6 but found it not working:

#echo hello > /dev/parport0
write error :Invalid argument”.

#ll > “/dev/lp0”
/dev/lp0:No such device or address

Any idea?

What does
Code:
lsmod | grep parport
say?

If that returns nothing, can you try
Code:
modprobe parport
and tell us the output?


Cheers,
Tink
