[Yaesu] FT-890 Data In and Out

[Jim Johnson - KC4HW]

Trying to help a friend with interfacing his FT-890 to a multi-mode 
terminal unit.  Not sure if I understand what the data in/out plug on the 
back of the radio is for. 

Is the Data In/Out for AFSK?  If so, I presume that the Data In is for the 
AFSK output of the terminal unit and the Data Out is the AFSK output to 
the terminal unit?  

Has anyone successfully interface a terminal unit to this port?  Certainly 
we could interface to the mic connector and the speaker output.  

Anyway, anyone got any help for us.  Thanks and HNY!
