Organized? Lines: 20 How practical is it to increase the packet size on a 'g' transfer? About 10% of a g transfer is header overhead (6 bytes header, 64 bytes data); it should be quite practical in terms of reliability to go to much larger packets (maybe as large as 1k, which works fine for ymodem) and reduce the overhead dramatically. My UUPC source indicates that it should be easy to go to at least 128, but the real question is whether any other site in the universe will do it. I haven't decyphered it enough to figure out if this is a negotiated parameter... if it isn't I guess I'm sunk. Do all known uucps run exclusively at 64 bytes/packet? (Yeah, I know it's only 10%, and probably only 5%. But if it's easy, why not do it?) Does anybody reading this understand the guts of 'g'? Doesn't seem like this should go on comp.mail.*, but there aren't any other groups that look good. (Besides, does anybody do anything else with uucp other than news and mail? :-)
