      Recently my T2-135 started working sporadically with my Garmin Nuvi 350. It would not accept commands from the Nuvi and finally stopped tracking stations entirely. I can't get a serial connection using otwincfg.exe. I removed the cover and when the Alinco Digital mode is turned on the T2-135 board's the red and green leds flash once. The degradation was gradual and intermittent up to the point where it now doesn't work at all. Any ideas?

        Thanks Lynn, tried that. Still get "Can't open serial port." It's less than two years old. Is there any warranty on these that would apply, do you know? Am a bit discouraged, as you might imagine.

          I don't think "Can't open serial port" is the T2-135. Are you sure that
          you a) have the right COM port specified, and b) nothing else is using
          it? Try opening the port in a terminal emulator (like Tera Term). If
          that doesn't work, then something else is owning the port. If that
          works, then cycle power on the T2-135 (via the Data Enable on the
          DR-135) and see if you get any text in the terminal emulator.

                      I believe the T2 is supposed to automatically detect the baud rate. The default is 4800 and that doesn t work nor do the others...

I opened it up and the T2 board's green and red LEDs flash when I put the Alinco in digital mode? Any ideas or help appreciated.

                        Keith, here s what it looks like: 9600 baud: ¡%ÿÿÿÿ8þ¡]7JPRS%»þ¡%ÿÿÿÿ8þ¡]7JPRS%»þ¡%ÿÿÿÿ8þ¡]7JPRS%»þ¡%ÿÿÿÿ8þ 4800 baud

                          Keith, here's what it looks like:

                          9600 baud:
                          ¡%ÿÿÿÿ8þ¡]7JPRS%»þ¡%ÿÿÿÿ8þ¡]7JPRS%»þ¡%ÿÿÿÿ8þ¡]7JPRS%»þ¡%ÿÿÿÿ8þ

                          4800 baud (default):
                          ‚9øÿÏøxˆÎY¹øÿøxHÎYøÿOø‚xˆÎY"€9øÿÏiiÄÀœËhü9øïO øxˆÎYê

                          Similar at other baud rates.

                          The T2 always auto detected my baud rate in the past. Never had it do anything like this until now.

                          And that s not in KISS mode, right? If you hold down enter, does it do anything? Scott

I can't get a serial connection using otwincfg.exe. I removed the cover and when the Alinco Digital mode is turned on the T2-135 board's the red and green leds flash once. The degradation was gradual and intermittent up to the point where it now doesn't work at all. Any ideas?

                                  Problem solved...

                                  I had a bad serial cable. (Murphy's Law)
                                  I didn't wait long enough for the autobaud to write to the terminal emulator. With new cable and patience I got the sign on and cmd.
                                  I didn't follow the directions for correctly connecting otwincfg.

                                  It now works fine with the Nuvi. Don't know what that was about but just thankful I'm back "on track" Thanks for the help and suggestions.

Other times it would track but would not accept commands. This weekend it failed entirely. I can't access/control it from otwincfg. I opened it up and the T2 board's green and red LEDs flash when I put the Alinco in digital mode? Any ideas or help appreciated.
