Advanced Serial Port Parameters

The Advanced Serial Port Parameters dialog box is used to specify communication settings for your auxiliary serial port. For most serial devices, it should not be necessary to specify these additional serial communication settings.

The Advanced Serial Port Parameters dialog box is also used to set the serial port parameters for laser range finders (Rangefinder tab of Rangefinder Preferences dialog box) and GPS receivers (GPS tab of GPS Preferences dialog box).
