Select Case Weirdness

[richard]

I'm thinking a case with no code in it is rather pointless (probably just confuses the compiler) and that includes thev "case else " too. what happens if you remove them

Most likely problem is in DTMF receiver, not select case...

Most likely problem is with code...
Think about it? How many digital lines come from the tone decoder that you are encoding? 4? Well that would equate to 0 - 15 combinations right? What you need to do is use the "data available" comming from the decoder as a qualifier for gating the case statement. Even if there are NO tones being decoded from the tone decoder there has to be some state the output lines are at right? Even if the output are "tristated" the input lines to the PIC when read will show some state. In other words, The NO CODE state is data NOT available....

I agree with Richard.
