In LOGic 9, the 990 use the Kenwood_850 driver. Probably the same for 8.
Let me know.
Tnx & 73,

Thank you Dennis, turns out the com port was being used in the data terminal, also the DTR boxes were not checked in Logic 8 in the setup. the driver mentioned above works on the ts-990s so all is well. Don
