Hi There electronic gurus.

I was wondering whether it is or was possible to connect a POTS/PSTN line into a laptop modem and use it as a DTMF decoder.

So in other words the phones or tones transmitted on the line would be displayed in a hyperterminal session?

I have a unit i built that can do it but someone mentioned that it can be done without the unit.

Many thanks in advance. What a wonderful forum btw.
