I have a few bare-bones systems running legacy software on creaking hardware. I want to be able to automate a lot of tasks by using auto hotkey scripts for tasks that currently, must be performed manually. I really don't want to install any software on these machines, and in some cases can't (as they are already maxed out on resources, or running Linux builds, or running weird stripped down Windows versions from the stone age)
I need a solution whereby I can receive keystrokes on a machine in real time without installing any software on it. However, requiring drivers or software on the machine sending keystrokes is no problem.
That's the problem I need to solve. Given the restriction on the receiving machine, I can only imagine that a solution might be along the lines of the input being via something like a Bluetooth dongle or USB receiver that registers as a keyboard, but is actually receiving keystrokes originating on another computer. If anyone knows if such a piece of hardware exists, could you post below? Or alternatively, any other solution that meets the goals.
