Hello All

to communicate thru' C i am using the outp() function for that but the
data i am sending is not reaching the port !
What may be the problem do i need to initialize the port ?

There is no such function in standard C. It is a non-standard
extension provided by your particular compiler, nothing at all to do
with the C language.

If it doesn't work the way you expect it to, you will need to ask
about it in a group that supports your particular compiler.
