I am curious about how this is accomplished; I don't see any
SIGSTOP-generating character defined in TTYLD(4) (standard
terminal handler line discipline).  Perhaps there is an extra
module slipped into place in your terminal stream; such a
critter could easily catch e.g. ^Z and post a SIGSTOP.  Streams
make it easy to add features like this; you could even have a
"Hazeltine tilde kludge" module..
