Hi Jon,
I guess in
interactive use most users would only miss one thing:
the history & line editing capability?
Job control?
Just as history and line editing were a possible enhancement to the TTY
driver, didn't Pike comment that job control was cooked up in foreign
climes because they couldn't drag out a new TTY window in pixels?
Was something like screen(1)'s ‘Ctrl-A c’ considered in the TTY driver
to spin up another pseudo-TTY rather than suspend the long job with
Ctrl-Z and ‘bg’ it?
