I've got a system with both serial and USB keyboard attached, and I

I've used hw.cnmagic to create a keystroke sequence "QQ" (0x51 0x51)
but it does not get me into ddb.

I don't think hw.cnmagic is handled by wskbd, but ctrl-alt-esc
should work with PS/2 and USB keyboards.

Unfortunately the kernel being booted has wskbd so Ctrl-Alt-ESC does not work.

I was able to get 'gdb -write' to work, although 'crash' did not allow me to write to memory.
