[WriteLog] Setting up WL with FT-2000

[N6WK]

Hi All, I just purchased WriteLog.
I am trying to set it up with my FT-2000.
I have my serial cable connected and I can poll the rig. No problem 
there. When I try to use any of the "F" keys, the PTT activates, but NO 
CW is being sent.
Can someone please advise what I am doing wrong?
My Yaesu software operates the rig just fine and my MMTTY software works 
great with it as well as Digipan and another logging program I own, but 
I can't get WL to send any CW. I am sure it is something I am 
overlooking, yet I can not seem to figure out what it is.
thanks,
Gordon
