Phule,
Sounds like the way I do it. I have a script that copies the buff-out.rc5 file to a floppy and restarts the client. When the in buffer gets close to running out of work, I download a large number of work units to a PC that has 'Net connection, then move that buff-in.rc5 file to a floppy, take it to the DOS PC, and import the file using:
dnetc -import a:\buff-in.rc5
(sometimes for speed I rename it buff-ina.rc5, copy it to the hard drive and do the import from there, as it is faster)
I do that as many times as needed to get a large input buffer so it can just sit there and crack away. 😀
