Extra keys on 122-key 5250-style keyboard are not working

[neilwaldhauer]

I am a beginner at Ubuntu. I apologize if I've posted in the wrong forum.

I have an Affirmative Unicomp model M 122 key keyboard. I intend to use it with IBM iAccess (ACS) to connect to an iSeries. iAccess seems to be written in Java and requires a JRE to run.

I have this working with a standard USB keyboard. But it has only 104 keys, and special keys for the iSeries, like F13 through F24 are simulated by shift F1 for F13, for example.

When I attach the model M (PS/2 connector), the standard keys work, but F13 through F24 don't do anything. I can still use shift-F1 for F13, but that is less desirable.

Is there some way to get the extra keys to function?

You can create keyboard mapping for each key to the working using something built into the display server. 5-40 yrs ago, we could have assumed you were using X11. There might be an easier method, but I tend to do things 'old-school', so https://wiki.archlinux.org/title/Xor..._configuration is how I'd attack this sort of thing.

BTW, I used to program IBM mainframes using an IBM 3275 terminal. 132-characters wide green-screen with multiple rows of F and PF keys. Those keyboards are like cockroaches. They will outlast all of us.

Today, you might be using Wayland. I think there must be Wayland tools for this, but I've never used Wayland https://github.com/xremap/xremap looks to be Xorg/X11 and Wayland capable. Could be the "easy way". IDK.
