Is the Write Control Character under control of the end user, or even
of the OMVS developer? I sense a political battle: "What need ...?"
Suppose there's extended computation with no terminal output?
Should the terminal driver routinely do the TGET NOWAIT after
every ENTER and save the data in the terminal input FIFO?
(Lock the terminal on FIFO overflow.) What does CMS do?
An example on MacOS:
596 $ sleep 10; while read I; do echo Saw $I; done; echo EOF
first
second
third
^D
Saw first
Saw second
Saw third
EOF
597 $
