Same thing: bootloader stuff on the serial console, kernel messages on the local computer only - and very slowly, at that, I'd say about one line a second. You could very easily see the characters being written to the screen. Am I the only one having these problems? It'd suck to buy a rather expensive (probably because they're pretty rare these days, plus I had to order from abroad) null modem cable and have it be completely useless. Regards, Thomas
