subject: SUPRA AT 33K6

AM>About 33k6 connections with Supra modems. I finally found a BBS
AM>here ni Italy that has another Supra 33k6 and I tryed to D/l a
AM>file from it. The first time I got a 33k6 connection in transmit
AM>but a 31k2 in receive, and a 600k long file was arriving with
AM>about 3450 cps. I tryed again a couple of day later, getting
AM>finally a 33k6 connection in Receive, but the RD light on the
AM>modem was flickering, not almost steady as it is when receiving
AM>at 28k8 or 31k2, after about 90k Trapdoor was giving me an offset
AM>error, and after restarting the transfer rate was remaining at
AM>about 3000 cps. It looks like that at 33k6 I've got more errors
AM>and consequently a lower cps rate than connecting to 31k2. I'll
AM>do further investigations, as it could be depending on the
AM>quality connection, but it seems that my modem works better to
AM>31k2 than to 33k6.
        That *CAN* happen.  If more packets are damaged and have to be
        resent between the modem, then the effective CPS rate will
        drop.  Just like talking very fast to someone in a noise
        place, if you slow down a little they have a much better 
        chance of hearing you correctly (but the trade-off it that
        it takes longer...assuming you *DO NOT* have to repeat 
        anything.  As soon as you have to repeat yourself, you're
        lost the time savings).
