I am having trouble getting my computer to talk to an FTdx5000. Previously, it was operating with an FT1000MP and the COMTSR statement (in the batch file) was "COMTSR1 -b4800 -n81 -rts" but this does not work. I have tried operating without rts (disabling it in the radio) - to no avail. Anyone have any ideas? John Evans, N3HBX
