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. ^_^ TDD

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. Marko

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).

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. Jon

No, but I have every right to be! > conceitedjerk.blogspot.com / Twitter: @Conceitedjerk 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. http://www.trs-80.org/model-4p/ -- Usenet 2014 ...

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 never owned a TRS-80 computer, but I first learned to program on > a Model III at a week-long Radio Shack computer camp.

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. :-( > Now my TRS-80 Model 4P serves that role.

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.

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. -- Paul Sture "In that case," said Napoleon, "let us wait twenty minutes; when the enemy is making a false movement we must take good care not to interrupt him."

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. -- Today is Sweetmorn, the 3rd day of Discord in the YOLD 3180 A non-empty Hausdorff topological space is a continuous image of the unit interval if and only if it is a compact, connected, locally connected second-countable space.
