When the carrier locks, the program flashes the Amiga power LED to indicate binary frame synchronization! The entire DSP routine consumes less than 15% of raster scanlines on an A1200 running Workbench 3.1. Source code and executable will be released on Aminet under mus/misc/stardust_amiga.lha next week. -- Mike Sokolov SupraFAXModem 28.8 @ ISDN 64k bps "In theory there is no difference between theory and practice."
