Terminal emulators

Posted by SaucyKnave95@reddit | linux | View on Reddit | 6 comments

Hey everyone. At work, we use a terminal emulator on Windows called "SimpTerm" for shop floor PCs to connect to the Data Collection server. The only thing special about this term emulator seems to be that F5-F12 are pre-configured to send Escape sequences. For example, F5 = \^\[OM, F6 = \^\[\[17\~, F7 = \^\[\[18\~, etc. I'm playing around with the idea of replacing the aging Windows computers with Linux Mint boxes, but I'm running into a problem with terminal connections. I've been using Linux distros off and on for 25+ years, but I feel totally lost. Can someone please help me understand how I can remap F5-F12 on a Linux terminal so they also send Escape sequences like I mention above? I've spent days trying to figure this out and I'm getting nowhere. This seems ridiculously easy, but I can't find a single shred of information on how to do this. Argh...

For whichever terminal you're using, in the Preferences/Settings look for 'keybindings'...in there you should be able to add your keys and the sequences to output when pressed. I just did it in Konsole, when I press F5 it outputs 'HELLO' :) Should work for any terminal.

Okay, Konsole works for me. I've got my F-keys rebound in a custom profile. This will work. I'll have to spend time looking at more terminal emulators, but this is good. Thank you.

You're welcome :) BTW, they don't like support questions being asked here, it's more for Linux news and such. Post questions on r/linuxquestions :)

The standard terminal (Gnome Terminal? If so, I don't understand why it's not labeled as such...) in Linux Mint 22.1 Cinnamon gives me no such option. It took too long to find the Terminal Preferences, in which "Shortcuts" are listed, but you can't edit those. Not in that screen, anyway. Konsole... is that KDE? This isn't a KDE vs Gnome thing, is it?

> The only thing special about this term emulator seems to be that F5-F12 are pre-configured to send Escape sequences. Thats not exactly 'special' - from my understanding, every terminal, sends escape codes as part of the text the F key sends. the receiving software the terminal is sending the codes to, uses the termcap features of linux to see what key got pressed. At least I think thats how it works, this is getting into some of the old-school deep depths of how linux (and the shell, and terminals) work. example: run the command `infocmp` and it will show some info. part of my output is.. kf1=\EOP, kf10=\E[21~, kf11=\E[23~ the \E is the escape code. So my terminal emulator in this case, sends` ESC O P` when you press F1 https://www.linuxquestions.org/questions/ubuntu-63/function-keys-in-the-shell-4175514670/ also check the output of `echo $TERM` What your function keys do is determined by the termtype you're using. if you could run 'simpterm' and see what termtype its setting, you could PERHAPS set the same termtype in your other terminal emulator, and the F keys MIGHT work the same as they would in 'simpterm' Googling for `simpterm` it seems its s very very simple telnet client. So it may be defaulting to a common terminal type.
