I use C-] as my screen escape key. Once in a blue moon I accidentally hit C-\ instead of C-] (with the predictably disastrous consequences). Frankly, I'm surprised it doesn't happen more often. Most of my keyboards these days have [ and ] inboard of t and y (Ergodox, 75-key ortholinear, Preonic (requires layer keys)), but I used C-] for literally decades before switching to ergonomic keyboards of these styles.

@elb I have an #ultimatehackingkeyboard and am quite happy with it. Never used a chord for Esc, and was somewhat surprised that #DEC vt* keyboards didn't have the key!

I use a IBM model M #keyboard on my #vt510 (which is a rare DEC terminal that accepts PC keyboards) and enjoy that experience, and the Esc key does work on it!

Tried an ortholinear #keyboardio but it was too hard to go back and forth between it and a regular laptop keyboard for me.


@jgoerzen I think that's a neat design, too, but I don't have one. I definitely like moving more keys onto my thumbs; I have space, backspace, enter, and delete on my Ergodox thumb clusters. I just looked, because I thought it did, and my VT100 has an ESC key. My Tek 4010 does NOT, though; it's a Ctrl+something key combination on that. I'm not sure ctrl+what, it's ASCII 63, so [ is shift+k; I'd have to check the manual.

@elb You have a VT100?! OK, you have won. Whatever it is, that wins :-)

duckduckgo.com/?t=ffab&q=dec+v is the sort of keyboard I'm used to seeing. That upper-left key isn't Esc by default. I'd have to go look up how it might generate Esc, because I forget. I blogged about the Esc issue at changelog.complete.org/archive and there are some comments on it there.

@jgoerzen this one is technically a VT105, it has (virtually unused) VT55 graphics modes.

@elb That is FANTASTIC! (Love the ssh to @SDF also; I've been a member for yeras) How did you get ahold of it?

@jgoerzen @SDF The terminal? It came in a lot of vintage minicomputer stuff I bought a couple of years ago. The PDP-11/34A it's _supposed_ to be hooked to is behind where I'm sitting when I took the photo. ;-)

I was on SDF MANY years ago, but lapsed, and have only recently rejoined. I love the idea of a shared Unix system like I used to enjoy when shared systems were a Thing.

@jgoerzen @SDF I try to rep SDF in my terminal posts since they're hosting my Mastodon. 🙂

@elb @SDF I do check the local timeline there about as often as the local timeline where I'm at. I wound up using a different Mastodon host due to the dated installation there at the time (since fixed) and some performance issues, but SDF is a fantastic organization (along side the Tildes)

Now if I could just get them to process my #UUCP feed request... 🙂

@jgoerzen @SDF Well, keep an eye on my feed for (I'm sure) more terminals logged into SDF; this is already number two. I hope to get a Tek 4012 up and running in the not-so-distant future, that'll be a treat. (I have a working 4010, but since it's ASCII 63, I can't log in anywhere!)

@elb @SDF The nice thing about your feed is that when my wife says "7 terminals from the 80s is excessive" I can always say "eh, it's not so bad. Look at this guy's collection!" 😁

Trouble is, I would love to have a vt100 and a teletype....

@jgoerzen @SDF I need you to document those 7 terminals for me so that I can use the same argument. "I don't have one of THOSE, though!" (Apologies if they are already documented and I just don't know!)

@elb @SDF Hah! Wyse WY-55 (green), IBM 3151 (amber), and five VT420s and VT510s in green, amber, and white. Some are all-original while others have new CRTs. All are in working order.

The VT510s I use the most, sometimes daily for "focus mode", due to supporting remappable keys and PS/2 keyboards. The IBM3151 is a strange beast, supporting "3151 mode" and "ascii mode" which have totally different firmware screens. Both work with Linux.

@elb @SDF I hook them to a Raspberry Pi 4 with Wifi, letting me have a mobile cart I can use to ssh to my main systems. It also runs GNU Screen, which solves the XON/XOFF issue with ssh (I presume you've run into that one also?)

@jgoerzen @SDF generally the XON/XOFF problem with vintage systems connected to modern computers is Real. I was surprised, though, to encounter it yesterday with apt search on my daughter's chromebook using the standard chrome terminal!

@elb @SDF Yes, the problem is that ssh puts the terminal into raw mode and expects the remote to handle XON/XOFF, which, when buffering and latency is considered, the handling of XOFF is too slow and overrun in the terminal occurs. Sigh. I really should build a DTR/DSR to RTS/CTS cable for the vt510...

@jgoerzen @SDF My problem is that so many vintage systems don't support hardware handshaking at all.
