You hit the nail right on the head Drew!
My ISP (Mindspring) has just updated my local POP (Melbourne, Florida) to
V.90 from X2. Using my USR X2 upgraded to V.90, I am able to connect at
50666.
I have experimented with the following K56Flex modems:
Motorola ModemSurfr,
Boca Research 56K Internal,
Wisecom Accelerator Pro.
I have tried using different versions of the same K56Flex to V.90 upgrade
protocol that's currently available (listings found on the 56K site:
http://www.56k.com/buyer/itu56k.shtml )
**Note: the Upgrade V.90/K56Flex "Wizard" as listed by each site will work
with just about any K56Flex modem (be sure to backup your firmware first).
The latest version I have seen is from the Genius 56K site (version 2.083,
dated 5-12-98). Updating each of the modems firmware, I have NOT been able
to connect any of the modems listed above at speeds over 28800. So, I
believe that even though there is supposed to be a "standard", it obviously
needs some fine tuning before all modems will in fact be equal in the V.90
world.
...Another interesting note here: When I connected to Mindspring before they
upgraded to V.90, my connect speed would always read 53300, with the average
file download speed being approximately 5.7K to 5.9Kbs. I am now connecting
at 50666 and the average download speed (using System Monitor) still shows
between 5.7K and 5.9K. Hmmmm, I wonder if USR kinda overestimated the
connection speed for their X2 protocol modems!
...One final note here: I originally sign up with K56Flex protocol ISP's in
my area using the above 3 modems. I could never get a connection speed
higher than 34000. My local Telco (Bell South) said that I had bad wiring. I
switched to USR and it's X2 after reading that Boardwatch article and have
been crusing at 50K speeds since then!
