Received an e-mail from a friend overseas who is having a problem sending CW via his LPT port.  This has been working in the past.  I don't know if any changes where made but I did have him confirm that the correct port and PC Generates is selected under the set-up menu.  It sounds as if the dots and dash are reversed.  He provided this example:

Example when keying CQ signal must be:
> ____---_-_---_-___---_---_-_---____ like this
> 
> But in our PC that signal goes like that:
> ----___-_-___-_---___-___-_-___---- that means key is always on when
> I not transmitting.

  Guess it could be the LPT keying module but he doesn't have a spare so there is no way to test that without sending him another.  Any thoughts?  It's tough troubleshooting this stuff from 7000 miles away and through a language barrier.

Thanks
