Hi you all. I'm developing an ADA program to control the parallel port on a PC. It seems easy, just as in C. The problem is I get some EXCEPTION ACCESS VIOLATION, everytime I try to access the address of the port. But the files compile OK. I'm stuck. ANybody has done it before? If you are interested I can send you the source code. Thanks in advance Carlos _______________________________________________________________ Do You Yahoo!? Yahoo!
