Hi again all, and a very Happy New Year to everyone.

My current problem is how do get a "freqin" type command working. I have a situation where I need to wait for 5 seconds and somewhere during that time I need to detect a 1200Hz tone, duration 100mS and then 1400Hz, duration 100 mS. Once detected, branch off and do other stuff, or if not detected at all, branch as well.
I have been experimenting and am getting nowhere. Second choice, does anyone know of a compiler, other than PBP (for pics) that does have this type of command?
Thanks, in advance.
