Why do I connect at 115200. Isn't the max speed 53333?
Some modems don't work
properly, and report the speed that the modem talks to the computer at (port
speed). because the modem is physically plugged into the computer, it can
communicate to the computer at a faster speed than it can communicate to another
modem across phone lines. When this happens, you can estimate the true connect
speed, by checking out
