Using an LK201 Keyboard via an adapter for a x86 virtual session

Post by raysangiorgio@yahoo.com » Tue Apr 16, 2024 4:40 pm

Has anyone found a good USB adapter to use an original Dec LK201 keyboard on a PC running the VMI virtual VMS system? I’d like to do a bunch of editing using EDT and really need a true LK keypad to rock,on. Thanks.

Have you tried experimenting with the PuTTy keyboard settings? Particularly Function Keys and keypad.
For putty, all I see a choice of pre-defined keyboard mappings (VT100+, VT400, etc) with no way to define individual keys.

I wrote a program to report the codes read by SMG$READ_KEYSTROKE and get different responses between VT100+ and VT400:
  • Find: 311 vs. 312
  • Insert Here: 312 vs. 311
  • Remove: 313 vs. 314
  • Select: 314 vs. 315
  • Prev: 315 vs. 313
  • Next: 316 vs. 316
  • PF1: null(numlock) vs. 256
  • PF2: 47 (/) vs. 257
  • PF3: 42 (*) vs. 258
  • PF4: 45 (-) vs. 259
  • MINUS: null vs. null
I can choose VT100+ and get the 'edit' keys (find, remove, etc) and have non-functioning PFn keys, or choose VT400 and have functioning PFn keys but scrambled edit keys.

F17 is intercepted by Windows as the windows key.
