The helpful soul sent me this:

I'm suggesting that if you have a slave CMD process and you have some set
of commands then you want it to execute for you, then you:
- use the UUID generator function to get an unique string
- pipe the commands into the slave and capture their output
- pipe echo abc12328fh8a (or whatever) as a signal
- wait for the signal text to show up on the slave output

Given that you don't see the child processes exit, you need to
know when you've got all the output from the commands that you sent.

Can't post to the list. Not from here anyway. I could subscribe
from home and do it there, but playing Forza Motorsport is more
pressing.
