Hello
I thought the point of the new modem code is not to give someone a faster
connect, but to give them a more reliable connect, with better throughput.
Maybe a graph of connect time before and after might be a better judge of
the modem code.
I agree that to this end, logging retrain and reneg counts to RADIUS might
be helpful.
USR and 3COM modems have always connected at too higher speeds.
When I used to work for another company selling non 3com modems (Microcom).
We used to demonstrate to customers a USR modem against a Microcom modem.
The USR modem would connect at 33600 and the Microcom modem would connect at
26400.
The Microcom would have twice the thoughput as the USR modem.
This is just to show that Connect speed is not always to best thing to
concentrate on. Throughput and latency(games) have always been the most
important.
Cheers
James
