input to parallel port prob

[tariq7868]

hello.. the prob is that when give status port a certain input and also to control port through open collector hex invertor,, the data output automatically switches to decimal value of '4' i.e (00000100) .. and also the 'init' (pin 16) of control port is not responding to any value. however when i give any value other than '0' to control port (0x37a) the init value responds...


ps: plz dont just reply telling to look for the query on parallel port in previous posts b/c i have and havnt found any so far. and also i hav googled as well..


thanks

Considering you pretty much ignored the fact this is a C forum and your question is about parallel ports and not C, I'll ignore your statement that you googled.

So with that said, find the documentation and check your program again. I'm not about to go rush off to figure out what you've done wrong... which is probably the problem. Oh, and one more thing... it helps to tell what "certain input" is causing unexpected behavior when you want to complain about it. Are we supposed to guess what input was given?

I always use my psychic powers to figure out what is wrong, and assume they'll use theirs to see what the answer I came up with is!

its ok... the problem is solved.i was using windows xp and borland c compiler..it was just that that there should be 1 assigned to every line of the output of control port then input values can fed...but thanks anyway..
