Using an EOT (^D) causes that shell to terminate.  Make a new window or
exit layers.  The keyboard might be "dead", but the mouse is still functional.

This can piss me off at times too.  Especially when I exit ksh(1) on my
main window, but fortunatly the window that is created using "new" is a
24x80 window and I can use vi(1) from it just as well.

Try rebooting the 630 without killing any processes.

Exit layers using the mouse. (see above)

I donno, maybe look for the "xt" and "layers" entries in the ps(1). (My system
says tty38 for a non-layers "window" and xt038 for a layers window.)

I use "layers -f .layerfig" to start layers. (.layerfig is a name I gave to my
layer configuration file)  I can make windows any size, change the PS1 ...
As far as saying LAYERS, *I* just look at the two little boxes in the top
left-hand corner.

Oh, what the H, here's my .layerfig:
