We may need to make some special provision for that aspect - we already do so for the early serial console support. The ldisc is the start point then there may be some bits that need to be extended around it. A bigger problem is going to be the fact non USB serial is vanishing bit by bit. We do have a USB console but it's truely crazy stuff and extending it scares me 8) -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
