I have been using a V32 9600 baud modem with SCO Xenix 2.3.2. The transfer to our feed is (of course) uucp. When checking figures for transfers I seem to get something like 500-600 chars per second. This seems a little pale to me. Is there any way to easily increase the speed of uucico? Like for instance changing the block size or something? Any tips are welcome. /svante -- Svante Gellerstam svante@kberg.se, d87sg@efd.lth.se

Try buying a Telebit modem, which includes UUCP spoofing, and watch throughput jump to 1300cps or so. -- Marc Unangst | mju@mudos.ann-arbor.mi.us | "Bus error: passengers dumped" ...!umich!leebai!mudos!mju |

Of course any comm connection is going to have to have like modems on either end. So you must go Telebit to Telebit. If you do that, and things are set up correctly, you should be able to see speeds up to about 1800cps or so. At least that's what I see here. It varies depending on the site on the other end, from about 1300 to 1800. That's outbound. Inbound, at least with Xenix's HDB uucp, I've never seen anything above about 1100cps. Anyone *really* know why this is? If you go V32 to V32 you should be able to see numbers in the 700-900cps range, slightly higher if your V32's have V42.bis. --Bill

I have found that the only reliable numbers you can use for the Telebit are the inbound figures. The Telebits tend to buffer the data on outbound transfers giving very unrealistic figures when uucico does its calculations. For example, I connect to a site on Saipan in the Pacific every night. We both have Telebit T-2500s. Both of us show outbound traffic at over 800 cps but inbound traffic between 200-300 cps. (Don't be fooled by these low numbers. At least the modems can make and hold a connection. The 2400 baud modem I have can't connect at all.) The difference between outbound and inbound seems to be simply the buffering effect of the Telebit on the outbound files.

With 2 Telebit`s you get about 1500-1700 cps - but only with two Modems at PEP-Mode with spoofing - otherwise you should use V.32 full-duplex Ciao Bernhard -- Bernhard Kroenung, Bahnhofstr. 8, D-W6408 Ebersburg/Rhoen, Germany +49 6656 386 horke@rhoen.in-berlin.de sysop@fulmin.zer.sub.org Kronung@DGIHRZ01.BITNET
