My objective here is to transfer a binary file between two systems with packet radio. The file will be highly compressed standard Email and NNTP posts - the old UUCP way of doing things. I believe the existing tools allow setting the size of the outgoing file bundle so we'll be able to limit it to something like 50K which would probably be fine for most of the exchanges. I'd like the transfer to be very fast, aggressive and efficient. To get the job done as quick as possible and get out of the way. No doubt that FTP/TCP would be better for larger and more robust transfers but in this case the overhead of TCP is unacceptable. I'm attempting to keep this scheme as standard as possible by minimizing the value added tools. A single specialized "ax25" file copy program that works through the AX25 tools would be a good solution. While this is basically Linux, I'm considering the issues and possibilities of running this on the other OS's. (UUPC anyone?) There's sure been some interesting info presented here in the past couple days... 73, Bill - WA7NWP
