I wonder if it might be possible to make an AFSK to FSK converter?  A
simple detector which would be driven from the soundcard output,
detecting the mark and space audio tones and converting them to a DC
level suitable for driving the FSK input?  Perhaps a PLL type circuit?

It might miss a cycle or two of the 2125 Hz audio during switching, but
I doubt if the timing is that critical.  What do you think?
