Two questions

(1) How do I turn off console blanking, i.e., what IOCTL. I need to
make sure that the last crash is showing on the screen.

(2) Alexy, you probably know this by heart. I thought that the port number
used in response to a TCP/IP connection request, was supposed to be a
"random short int with a value above 1000".
This is what I get:

        204.178.40.224:32790 -> 204.178.40.137:23
        204.178.40.224:32789 -> 204.178.40.137:23
        204.178.40.224:32788 -> 204.178.40.137:23
        204.178.40.224:32787 -> 204.178.40.137:23
        204.178.40.224:32786 -> 204.178.40.137:23
        204.178.40.224:32785 -> 204.178.40.137:23
        204.178.40.224:32784 -> 204.178.40.137:23
        204.178.40.224:32783 -> 204.178.40.137:23
        204.178.40.224:32782 -> 204.178.40.137:23
        204.178.40.224:32781 -> 204.178.40.137:23
        10 connections

It certainly looks like "randomness" has been removed. Is this correct?
It's been several years since I looked at the RFQs, but this does not
look good. I can certainly predict what the port number for the next
connection will be...

Cheers,
