[KDB+/Q]: Reattach Windows console to a background running q process

Assuming there is q process running in the background after launching it with system command:

$ q
q) system "q -p 5000"
q) \\
$

How can I attach my Windows console (cmd or PowerShell) or terminal multiplexer (such as ConEmu) back to that process, so that I get:

q)
q)\p
5000i

I found a similar question here: Windows equivalent for Linux "screen" or another alternative?

The asker is looking for a windows version of the Linux screen command, which I think would be what you are looking for. Unfortunately there doesn't seem to be a native solution but you should read through it and see if it sheds any light on the topic for you.

A workaround using IPC, connect to the process from a new q session using:

q)h:hopen `::5000;

Then pass the command through to get the information you need.

q)h"sum 10 20"
30

Here's a link to the kx IPC cookbook for more info on IPC: http://code.kx.com/q/cookbook/ipc/

Hopefully some of this is useful to you.
