I agree that there is a software problem, but the software problem is exacerbated by certain hardware (I described some of this). It is not correct to say that the Dec. kernel doesn't work on a 4 port. I'm posting this from an RT running the Dec. release; the serial ports are on a 4 port. Of course I should point out that this is a buffered 4 port, it is possible that it doesn't work at all on the unbuffered. I would be the last one to claim that it works well - I crash about once a day getting news, but it does work. Anyway, it's good to see people complaining about the 4 port in a public place since this may force someone to fix the problems the RT kernel has with serial support.
