- USR's firmware upgrading utility (the SDL program) changes the DTE
- rate of your serial port and modem. If your serial port is locked at a
- specific rate then the upgrader will fail. This is normally only really a
- problem with people running the SDL program in a Dos Windows or OS/2
- session (or anything similar to that), since plain old DOS doesn't do
- anything to prevent the software from accessing your serial port hardware.
