                                <div>Hi Doug,<br>
                                  <br>
                                  Never did get a response. Was trying
                                  to avoid reinventing the wheel.<br>
                                  <br>
                                  Never thought of using the patch
                                  command to do DTMF stuff. Will do some
                                  investigating.<br>
                                  That's the cool thing about
                                  Allstar/Asterisk, if you can think of
                                  something, there's usually a way to do
                                  it.<br>
                                  <br>
                                  All your efforts are really
                                  appreciated.<br>

                                      In researching I saw you asked the
                                      same question years ago and I did
                                      not see an answer then. Did you
                                      ever get one?<br>

                                      <br>
                                      Using the GPIO on the Pi to BCD
                                      control a radio would not be hard.
                                      In fact a user has already done
                                      that using function codes and an
                                      external script I wrote to control
                                      the bits. It is in use
                                      commercially.  <br>
                                      <br>
                                      The idea for the future code we
                                      are writing is to get specific
                                      stuff out of the base code and put
                                      it where users can create their
                                      own interfaces to whatever
                                      hardware they want.<br>
                                      <br>
                                      Here are the basics of how I would
                                      do it....<br>
                                      <br>
                                      Use the patch command (with a
                                      different code) to pass DTMF to a
                                      Linux script via an
                                      extensions.conf dial plan.<br>
                                      Then the script would take the
                                      number sent, convert it to BCD or
                                      any other format the radio
                                      requires<br>
                                      and send it to the GPIO bits. Of
                                      course you would have to interface
                                      those bits to the actual hardware.<br>
                                    </font><br>
                                    <font face="Tahoma,sans-serif">If
                                      you needed to pass a code to a
                                      remote node you would use the

                                      to the remote nodes dial plan.</font><br>
