      Keith, Scott and Mike, thanks for the suggestions. When I pulled the
      cover, I discovered the connector from the DB9 to the T2-135 was loose
      in the socket. I reconnected it and regained (some) connectivity.

      Both LED's do blink when the power is applied.

      Mike, I like the idea of hot-melt glue on the connector - the kind I
      have can be peeled off pretty easily, so it could be undone at any time,
      but should hold against vibration, etc.

      I said (some) connectivity, because getting the config program to
      connect to the T2 and display the config screen is tenuous at best. It
      seems that it will connect maybe 1 time out of 10 attempts. I'm using a
      laptop with a built-in RS-232 port (IBM T30). I also tried with a USB to
      serial converter on the laptop that uses a FTDI chip that's never failed
      to connect to anything that I've thrown at it. (And that's been quite a

      I've tried power cycling the radio, both using the ON/OFF button on the
      radio, and pulling the power connector, and it doesn't make any
      difference. The message I get is "Can't open port" or similar.

      Any thoughts?
