[Yaesu] FT 920 AND Kam for cw

[Tim]

Could anyone help with this one, I have an FT-920. I am currently using an external keyer and have the internal keyer off.
Everything works great. Now the problem, for some reason I cannot get my Kam plus to key the rig in the cw mode.
It works on receive. I have the din plugged into the kam and the other end plugged into the FT-920 but it does not key.
I checked all I know to check in the kam and the FT-920 but I am missing something. 
The software I am using is Pacterm 98. What I am trying to do is, the wife would like to upload files in pacterm 98
and have it sent to the rigs key so she can tape them. She wants some different cw to listen to going to sleep at night.
For this I thought it would be in my best interest to get this to work. (Maybe I could tell her only the FT-9000 will do this !!)
Thanks so much
