Grab an old TTY decoder program and you'll see how it's done ...
pretty trivial, really. The rough part (for me, at least, since I've
never tried it) is getting the sound card to tell you which frequency
it's hearing. But once you have the digital train decoding ASCII is
no job at all (0100 0001 is upper case A - no "decoding" needed), and
decoding Baudot isn't much more complicated (keep the current shift
state in a boolean and look up the character in a table).

Have any web locations for older decoders with source? I've been
looking but cant find the source, realizing its mostly in
visual basic I think. But moving it over to something else shouldnt
be that hard.

TIA
