I was having some problems compiling SIMH on FreeBSD.
The reason is, all
the sources have stray MS-DOS carriage returns (^M), while UNIX only
uses line-feeds (^J). This causes GCC to misread some of the code. I
suggest you convert the sources to UNIX text format.
use 'unzip -a' to
automatically convert text files when unpacking.
BTW, why is networking not supported on FreeBSD? Does
the pcap driver
not work?
on FreeBSD you can't send packets directly over bpf (at least not
the same way you can on Net-/OpenBSD). I have patches to make it
use libnet for sending packets. It's a bit rough, but it works. I
can put them up somewhere if anyone is interested.

FreeBSD certainly does let you send packets over bpf. If you open the
device (e.g. /dev/bpf0) for both reading and writing, you can write()
a buffer to the device, and the contents of that buffer will be sent
verbatim from that device. I do this all the time for protocol
testing.
I'm not running NetBSD or OpenBSD currently, so perhaps they support a
richer interface than FreeBSD does, but the essentials are indeed
there.
