[WL-USERS] FSK Stop Bit Setup

No problem. I was just cautious, as I said, in making the fix available to
others in case there had been a problem I'm not aware of.

Michael, you may be right. When I checked Waynes msg it had a [WL-USERS]
in front of the FSK Stop Bit Setup.. I listed it again in case it wasn't
listed before.. Thanks for keeping me on the right track.. I do forget
