In principle its not difficult to do it the data rate is low enough, anything much over V.22 would be trickier and anything aproaching more than a few kilobits/second needs a faster processor or dedicated hardware.
I was thinking you would be able to get a greater baudrate at the cost of higher bit error rates using QAM* or QPSK** rather than FSK for not much more effort in terms of coding. *Quadrature Amplitude Modulation **Quradrature Phase Shift Keying |
