the transceiver has not responded, and the serial port's RTS signal is not set to 'on" , which this transceiver typically requires; set the RTS signal to 'on"?

+ Thanks, Saad. Both your FT-2000 and your TS-2000 require RTS to be enabled. Failure to properly configure setting in Commander this is a "hole" that new users who don't read the appropriate section of "Getting Started with DXLab" fall into, so if either is your primary transceiver but the Primary CAT Serial Port's RTS selector is not set to "on", then the "reminder" is displayed.
