it's not possible to upload files to this forum. You have to link to images stored somewhere else.
I was thinking that it might be useful if you could provide an unaltered .wav recording of a "real" 2000 baud program, you'd be surprised what can be learned just by comparing .wav files in an audio editor.
That might be the fastest way to help if you don't have much time.
(just thinking out loud, of course I could be wrong and the last thing I want to do is to waste anyone's precious time)
