I'd argue those are differing situations, though. Bell 103 and Bell 101 modems use the same AFSK frequencies, just at different speeds. Bell 202 modems have specific hardware to support Bell 103, effectively two modems in the same case. -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckai...@floodgap.com -- Excellent guess, Kreskin.
