Last change on this file since 199 was 199, checked in by gregli@…, 13 years ago

Adding proper serial port support to the Configurator, which required some minor changes elsewhere. Also added an option, off by default, to automatically scan for serial drives at the end of normal drive detection (no ALT key required, although that is still available if the option is off).
