Is it possible to open a shell in a coroutine and just interact with

So in a coroutine, I would just open it and then read and write then
yield?
As Dirk wrote, `io.popen` is read XOR write.
If you're on some unix-y system & depending on what you're doing,
lpty[1] might work for you.
There may be "simpler"[2] ways to do that, but so far, for me, this was
the "simplest"[3] way to get non-blocking bidirectional communication going.
