I totally agree with Paul, the onboard serial device should get ttyS0 regardless of what hardare is used to drive it. We dish out the minors sequentially on sparc in order to handle the case of multiple onboard serial controllers of different types which can happen on sparc. Generalizing this minor number allocation for ttyS? might be the best way to handle this. - 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/
