Yeah this was a while ago. ;) My experience was that zmodem was incredibly fast under real-world conditions. It really was like getting a speed boost on your 300 or 1200 baud (or 2400 baud, if you were lucky!) pipe. Anyone remember xmodem or ymodem as well?<p>EDIT: I didn&#x27;t realize he&#x27;d written ymodem as well! What a brilliant guy.
