Erik, in fact, there is a special USB (EHCI) mode for such purposes: http://www.coreboot.org/EHCI_Debug_Port But that requires some special HW in addition to SW support which our doesn't have. BTW, Ronald, it is possible that you might have a serial header on motherboard which is not connected to any traditional port. -- Andriy Gapon _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
