Your add-ons are started within the add-on server, and therefore they share the same standard input/output channels. IIRC PRINT will just dump to stdout - which might not help you, also you need to compile your add-ons with DEBUG=1 to see any output. There are two things you could do to make your system more vocal, though: 1) use SERIAL_PRINT() for debug output instead (or _sPrintf() directly, as defined in os/support/Debug.h) 2) replace /dev/null with /dev/dprintf for redirecting output in the Bootscript HTH, Bye, Axel.
