That was related to OpenFirmware serial console behaivor, which would be unrelated to the Juniper BIOS (for x86 systems) or U-Boot (for the other) behavior. It didn't have anything to do with the OS that was running. Also, Solaris is System V, not BSD (/usr/ucb notwithstanding). On OpenFirmware, sending a BREAK would drop the system to the firmware prompt, which stopped the running OS (the firmware was essentially always loaded and "running" in the background). BIOS and U-Boot systems don't operate like that (well, there are things like SMM, but that's different). -- Chris Adams <[email protected]> _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
