Unintended Symbol Shift-lock or other missbehaviour when using PS/2 keyboard
I'm running
Component | Version |
---|---|
Firmware | 1.43 |
Core | 3.01.10 |
Basic | 2.07l |
Being a bit lazy when switching the input mode of the system, sometimes the keyboard gets stuck.
When switching to Extended Mode and back using CTRL and Shift on my PS/2 keyboard sometimes Symbol Shift or Caps Shift gets stuck or the system is receiving continuous characters.
This can be disabled only via hard reset. When executing a soft reset (by shortly pressing the RESET button) the keyboard still got stuck or is in Symbol Shift-, or Caps Shift Lock which can't be disabled.
As for long time I didn't find a way to reproduce this I haven't added an issue before.
Now hopefully I've found a way to reproduce the behaviour:
(All inputs to be entered using a PS/2 keyboard.)
- Switch On the Next
- Enter the Command Line
- Press and hold Shift
- Press and release CTRL
- Press and release H
- Press and hold CTRL
- Do not release Shift or CTRL until the system starts the keyboard repeat sound
- Release Shift
- Release CTRL
If you are lucky, Symbol Shift should be locked... ;-)
