Re: Bidirectional parallel port
Did you write your own drivers?
There are two reserved bits in the Control register (highest 2 bits 6&7). I've
found that some computers require these to both be set to logic '0' for
bi-directional mode to work.
So if you read in the control bits, change a bit, and write it back, make sure
that the 2 highest bits are '00'.
Just my $.02.
