Nothing fancy, just 16 channel stuff. GM300, Maxtracs, Kenwood 90
series stuff. Just got to yank the lines low. <br>

What is the format of the BCD control you are wanting? 16
channels - 0001 - 1111 ??</font> <font style="" face="Tahoma,sans-serif"> Does the radio take TTL levels? Is

<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">

<font style="" face="Tahoma,sans-serif">If you needed to
pass a code to a remote node you would use the standard
codes to pass the command to the remote nodes dial plan.</font><br>
