Look at sup's line usage sometime - you'll see a frenzy of activity, then a long lull while the local sup looks over what it's got. It also doesn't seem to transfer the data very quickly when it does, but that's another problem. It and the supfilesrv should be running threaded so that sup queues work to be done over the line at all times; if it's thinking about what should be xfered next, it should do it while still copying over the last files from the previous batch and the supfilesrv on the other end should be able to accept more work while it's still sending files. To make it plainer: I want that 14.4K line saturated constantly. When I run sup over my serial line, I want to have it OVER as soon as possible. Eyeballing the modem lights while sup is doing it's thing clearly shows me that this is NOT currently the case.

Agreed, the client side might be easier to setup, but that should be Not trivial enough that people interested in running mirror sup sites haven't all sent me mail saying ``how the fuck are we supposed to use this damn thing??''. Reader feedback indicates that it's not fairly trivial to set up. But since you seem to think so, I think I'll point the latest querant at you! :-) Jordan
