I posted a pretty detailed explanation of this about a month ago, so won't repeat it in excruciating detail here, but the summary is that the 57600 you're seeing is because the new modem is configured (changeable through software) to report the speed at which it's talking to your computer (known as DTE rate "Data Terminal Equipment"). 28800 and 26400 are DCE rates ("Data Communications Equipment"). DCE rate is the speed at which your modem is talking to the other modem. Computers typically talk faster to their own modems than the modems talk to each other because modern protocols allow data to be compressed by the modem as much as 4:1 before it's actually sent over the wires. Someone mentioned throughput versus connection speed earlier. They were correct to a point. However, the connect speed is not to be discounted. If you connect at only 14.4k, you'll get throughput no higher than that except for gains from compression. It's possible for today's modems to re-adjust their speeds after the connection has been made, but it's rare this happens. For it to happen, both modems have to be configured to let it happen (most aren't by default) and the line quality has to improve mid-session. A big part of that noise you hear while a connection is being initiated (called "handshake") is each modem bouncing signals off the other both to determine the maximum speed they both speak and to determine the highest rate current line conditions will support. It is quite common to have the switching equipment between two locations be different enough to cause a major difference in connect speed. My broker, who lives in a new development just 15 miles from me, can rarely get connected above 14.4k using the same ISP I am and the identical modem. I usually get 26.4k connection with occasional 28.8's. Sorry. Got long-winded again. <grin> Not a lot of things I'm an expert in (especially trading/investing), but if you cut me, I bleed "carrier", not blood. L
