[Ham-Mac] cocoaModem FM Hell 245 Mode?

[Dick Kriss]

I just had a good QSO with EA3AQS on 20 meters using the FM Hellschreiber
245 mode. Rock solid copy both ways but he indicated my signal was inverted
or white background with solid letters vs. black background with white
letters.  I did a quick scan of the cocoaModem users manual and it sounds
like I should be sending a solid or black background.  I must have something
set up wrong to invert the colors.

Any FH Mac users out there that can help?  I think it is only inverted when
I use the FM Hell 245 option.
