When modems connect some of the squealing you hear is the modems negotiating
what speed they will connect at. Factors are the speed of the modem on the
other end, and the line conditions, among others. The modems can step down,
~fallback~, to a lower speed, dirty lines will result in a lower connect
speed and can also result in the modem dropping the connection, it just
gives up trying to handle the errors. Modems can also be forced to not
fallback, this is best used to force a redial to get a cleaner line,
normally only a concern for those in rural areas where lines are usually
poor. Some modems are better than others at handling line noise.
NOTE: Some 56K modems default to 26600 when they are unable to connect
properly.
