Well, this is not really PIC related, but since someone brought
it up...  I have seen boxes advertised that will take a modem phone lin
plug and plug it into a telephone handset connector.  This is typically
used with digital office phone where who knows what is on the line cord.
        What I'd like to see is an acoustic coupler that I could use with
my notebook computer to pick up email at pay phones.  Pay phones
generally don't give us access to any direct electrical connection.  Any
acoustic couplers still being made?
