Lars: '<=>' denotes bidirectional signal flow and is the symbol intended to correspond to IO pins as opposed to IN or OUT pins. Remember, though, the quote from the docs in my earlier message---these direction-indicator symbols are merely a convenience to the user. They don't communicate any information to LinuxCNC. The reason I get downright pedantic about this point is that we users are so used to the symbols we forget they may lie to us. If the HAL configuration file was generated by LinuxCNC from a loaded configuration then the symbols are correct according to the component declarations known to HAL. If the file was generated by a user using an editor then they may or not be correct. It won't matter to HAL when the file is parsed (although the actual pin connections will) but it would confuse a user who tries to make sense of the file. But you've already solved your problem, which is the important part of this thread.
