After talking with the person who originally did the patch, yeah, that does make sense (and the serial driver we're using needs to be fixed).

That wasn't working here however. Unless minicom isn't sending the proper break. Doing the keycombo which slips my mind to send a break, followed by 'h' in minicom does nothing. -- Tom Rini (TR1265) http://gate.crashing.org/~trini/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

It is handled at the serial port driver level, not the tty level. You need to turn on CONFIG_SERIAL_CONSOLE and CONFIG_MAGIC_SYSRQ, and issue a break followed by the relevent character within 5 seconds on the serial TTY being used as the kernel console. -- Russell King ([EMAIL PROTECTED])The developer of ARM Linux http://www.arm.linux.org.uk/personal/aboutme.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
