Most OSs still support a shell login via a serial port. Does anyone out 
there still have a dumb terminal and a serial port, and still use to 
connect to a system?

I was using a dumb terminal to program phone systems and even gave on to 
some friends of mine to use to program phone systems. I later used my 
Dell laptop which had a serial port to program phone systems, control 
systems, routers and managed switches. Now I have a USB to serial 
converter to accomplish the same tasks. I do believe I have several dumb 
terminals in storage an perhaps one out in the shed. ^_^

Oh yea, the laptop is a lot easier to carry around. ^_^

I used to have what I think was some version of an ADM 1A, but 
eventually the electronics deteriorated. It was kinda fun getting it to 
run with a modern system and figuring out the termcap etc.

A computer urnning a terminal emulator is just as dumb as a standalone 
dumb terminal.  Get a Mac Classic and you have cute little terminal for 
whatever purpose that might come up.

I wish I could use a virtual serial port to fully automate the
installation of Linux on a virtual machine. Some VM platforms have
commercial support for serial/SSH translation, but I have never had the
time to try it. For example, I don't know if the modern mainstream Linux
distros will install on a headless PC.

Yes, you can do headless install of Linux with kvm/libvirt:

    virt-install --name c70 --ram 1024 --nographics --os-variant rhel6 --network bridge=br0,model=virtio \
        --disk path=/data/vm-images/c70.img,size=8 \
        --location /data/mirror/CentOS/6/os/x86_64 \
        --extra-args "ksdevice=eth0 ip=192.168.57.70 netmask=255.255.255.0 ks=http://192.168.57.3/c6.cfg console=ttyS0"

You can also redirect the console output to a unix socket with an
option like "--serial tcp,host=:2270,mode=bind,protocol=telnet".  I
have done this in the past and used conserver to log the console
output.

Recent versions of FreeBSD have broken the headless installation on
the default .iso image, but this can be restored with a minor patch to
the .iso (echo 'console="comconsole"' >> boot/loader.conf and rebuild
the .iso).

On sparc64 at least, the FreeBSD installer gracefully fails over to using the 
serial console if the serial line catches user input before the keyboard does.
Given that I keep my Ultra 5 headless, with a null modem cable to an RPi 
attached to it, that's not a really pressing race condition.

I used an old off-brand VT-100 clunker until recently, when its CRT finally
died.  I used it to maintain my ancient Cisco 2501 routers on my private
network and occasionally for shell access to my many boxen.

Now my TRS-80 Model 4P serves that role.  (Yes, I'm serious)

That was a nice machine with a big screen (for a luggable, anyway).
Seems like it would make a perfect terminal. Does yours have the
original black/white screen or the green screen?

I never owned a TRS-80 computer, but I first learned to program on
a Model III at a week-long Radio Shack computer camp. Later, when
I was in high school, I used to look for the 4P in every Radio Shack
I entered. I remember feeling disappointed when my Dad bought a PC-XT
clone for himself instead of one of these. :)

Here's a nice writeup about the 4P.

Mine has the green screen, and newly-installed 360k floppy drives!  It's
less portable nowadays since I added a 70 meg full-height 5-1/4" external
hard drive, which added 15-20 lbs to an already heavy portable.

I didn't get mine 'til 2005, after 30+ years of coveting!  I cut my teeth
on the Coco 2 (my first computer), then the Coco 3 til I upgraded to the
Amiga, then PC.

Always a good site, although I miss the downloads section...

I had a couple of genuine DEC VT220 terminals until I emigrated in 1998,
when I reluctantly left them behind.

When PCs still had serial ports I used a VT100 terminal emulator to
talk directly to serial ports on routers, but the last router I had
with a serial port was an ADSL model so useless with cable. :-(

If it still works, why not?

A related question: does anyone still produce this stuff?  I have a
strange nostalgia for amber or green screens, and just had a set of
personal business cards printed up with VT-100s as a background image.

I see tons of refurbished stuff on ebay etc. but surely there are
systems out there that are working just fine on that era's technology
and sees no reason to upgrade to anything else.  Perhaps there's a niche
market for new/compatible terminal hardware?

It kills me to see clerks/etc using a WinXP box with a terminal client
like PuTTY open.  They're invariably also using their terminal to surf
the web or chat on MSN Messenger at the same time, the sort of thing I'd
not be happy about if I were an employer.

I'm not sure though I've found a link for some VT520s here:

When I worked in a factory there was nothing better for production line
use than a VT of one flavour or another.  We blocked off setup keys to
stop users fiddling with them so they were pretty maintenance free.  You'd
probably have to do quite a bit of locking down on a PC to achieve the
same level of robustness.

I used to do process control automation for a crisp (US: chip) and biscuit
(US: cookie) manufacturer. We had ruggedised VT100 clones with custom
keyboards in the factories for the operatives to use.  I imagine a PC
would have lasted a couple of days tops in the hot, greasy, "dirty"
environment of a crisp (US: chip) factory.

Up until October of 2012 I could use a dumb terminal to call my ISP and 
use the shell there.

If I had an emergency, I could dig out the modem, run a long phone line to 
a plug, and call the Ottawa Freenet where I have an account (for Usenet) 
and use their "shell" (which is actually a very limited selection of 
tools), all with a dumb terminal.

Check the apple II newsgroup, people sometimes use their Apple II through 
a serial port to their main computer to get on the internet.  I'm sure 
that applies to others running older computers.

My mom just shipped my IIGS out to me.  I can't wait for it to arrive, 
and get it hooked to my OS X machine.  My only issue is that I want an 
LCD display for it - the old monitor seems like it's on its last legs.
