perhaps i wasn't clear. a 1 meg uncompressed file (like wav or txt) would be faster to download on a 56 k than a compressed file like zip or mp3. this is because while the 56k is downloading, it compresses the data being transferred (not exactly sure how it does it) so in effect the 1 mb uncompressed file turns into a 500 or 700 kb file still being transffered at whatever speed it is. the maximum physical speed is still 7kb/s (in North america it's actually around 6.2 because of the limitation for fear of interference; sk8punk151 was at least right about that plus overhead so don't expect over 6 and realistically, if you have extremelly high-quality phone lines in your house and between you and the provider, you can expect 5 kb+) back to what i was saying, both 1 MB of uncompressed and compressed data still transfers at the maximum but it will seem like the 1 MB uncompressed will transfer at a much faster speed because of the modem compression. This is quite useless for faster speeds however and was removed in high-speed modems because there are very few files that are uncompressed and the amount of compression achieved probably doesn't play a significant role when your transferring at 80 KB/s +
