<div class="ecxmoz-cite-prefix">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>

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 id="ecxFontBreak">

code to a remote node you would use the standard codes to pass
the command to the remote nodes dial plan.</font><br>
