There is absolutely TCP/IP in Ultrix-11. This is an emulated 11/23+:
hrb11# uname -a
ULTRIX-11 hrb11 3 0 PDP-11/23
hrb11# ifconfig qe0
qe0: 192.168.1.199 netmask ffffff00
hrb11# netstat -rn
Destination Gateway Flags Refcnt Use Interface
220.127.116.11 192.168.1.1 UGH 0 0 qe0
192.168.1 192.168.1.199 U 1 0 qe0
default 192.168.1.1 UG 0 0 qe0
192.168.5 192.168.1.1 UG 0 0 qe0
hrb11# ftp 192.168.1.63
Connected to 192.168.1.63.
220 aelfric FTP server (Version 6.4/OpenBSD/Linux-ftpd-0.17) ready.
It has trouble talking to the outside world, probably not a big surprise,
but works just fine on my local network. I am working on getting it
installed in a real 11/23 but the Ultrix RL02 driver doesn't seem to like
my Dilog emulation board.
