... and it's the issue. It's not only problem of SSB if you want use a 
micro directly connected to the TRX but also CW if you want use some 
from WT independent key. The difference in your case is the using of 
Winkey - it's directly controlled by WT and therefore WT provide also 
the correct information to the parallel port.

It seems that the parallel port doesn't provide at the moment the 
complete information about selected radio.

Larry can you check please if there is a hope to change the logic of the 
parallel port at this point?
