Well, I looked at the manual and saw this in console(4S):
ESC[s Reset terminal emulator (SUNRESET)
Takes no parameters. Resets all modes to default,
restores current font from PROM. Screen and cursor
position are unchanged.
So I tried it.
Be warned that on a 4/110 running 4.0.3, this sequence panics the kernel!
Is this a known bug? I get the following crash:
