[HECnet] Announcing TCP/IP for RSX-11M-PLUS

[Johnny Billquist]

Hi.
The turning off of TCP/IP is a big kludgy, and do not properly handle if 
there are active connections.

I would, in general, recommend that you just leave TCP/IP alone, and it 
will stop when the system halts.

One day I'll get around to "fix" that part, but it's a low priority thing.

If you want it to shut down cleanly, you need to check with NETSTAT/ALL, 
and the list needs to be totally empty before you run IPREM.
