The threads on V.32bis have gone in, out, up, down, and every other way... What kind of throughput can one expect on compressed files over V.32bis ? From the discussions, I gather that it does not degrade below 9600 because of error-correction, flow, etc... I also gather that it does not take advantage of compression, an d thus does not exceed 9600 ? So...will compressed (or randome) files pretty much stay at 9600 baud throughput ? Thanks --- Robert

I get about 1610 cps, average, on compressed (zip) files. I get about 1100 with straight V.32.

If I use V42, I get 1680 cps. I still get my best times on my USR Dual by using HST and MNP-4 with no compression. This combination gives me about 1729 on ZIP and GIF files. -- Bob Mathias uucp: ccicpg!uis-oc!bob@uunet.uu.net Unisys Corporation CServ: 70340,165 A and V Series Systems Engineering voice: (714) 727-0323 Irvine, California
