If you have been forced to connect to a "traditional UUCP" site, this may have been a useful concept. With a packet size of 64 bytes and max. 3 windows, the protocol was OK for 2400 baud, but not really usable for faster modems. My enhanced packet handler supported dynamic packet sizes between 32 bytes and 4096 bytes and 1..7 windows. Given that I could update the UUCP implementation of my news-feed in the university, this was a better solution than the Telebit protocol spoofing. BTW: UUCP enhancements have been discussed by many people in comp.mail.uucp Active people in that group have been e.g. Ian Lance Taylor various Rick Adams t protocol for TCP/IP Matthias Urlichs e protocol. similar to t protocol Peter Honeyman g protocol description Jörg -- EMail:joerg at schily.net (home) Jörg Schilling D-13353 Berlin joerg.schilling at fokus.fraunhofer.de (work) Blog: http://schily.blogspot.com/ URL: http://cdrecord.org/private/ http://sourceforge.net/projects/schilytools/files/
