DTMF Application Kit ????

Archiver

I am considering using the CM8880 DTMF transceiver kit in a ham
radio application as a multi-purpose DTMF decoder. I would like to
set it up where a DTMF string of "123" would enable an output, "456"
would turn it off, etc.

I am looking for any information on how to write the program to read
the 4 interface lines from the CM8880 and store each decoded digit as
a variable then do a comparison to see if the correct digits were
received in the correct order.

Thanks
