Zipped files are already highly > compressed, and cannot be much further processed. some stuff that is misunderstood by computer newbies: 1. "bps = baud." this was only true in the early modems. 2. Bps vs bps. Bps usually refers to bytes per second. 3. the line speed is limited by Shannon's theorem. http://en.wikipedia.org/wiki/Shannon's_theorem 4. line speed vs throughput. http://en.wikipedia.org/wiki/V.44#Error_control_and_data_compression 5. UART caps.. http://en.wikipedia.org/wiki/UART
