NonTormach Lathe HAL problem, door and limit inputs

 How are you configuring door and limit switches in your HAL files? I'm stuck. 

On PathPilot lathes use multiple frequencies on one input pin (freq2pin) to monitor multiple functions.  That includes the door safety switch, and homing/limit switches.  

What are we doing to get around this problem? 

I'm trying to follow this guidence, remap limits and door switch to the pins that are designated for Probe and Toolchange Input.

I'm studying the LinuxCNC HAL guide. I'm just not fully sure how to do this correctly. ?

My big lathe problem is that freq2pin is assigned to a pin that is an output on bobs like cnc4pc C10

can you post your existing hal?...

I remapped the door switch to a physical input on my lathe, the tool changer side of things has a pwm (period measurement) output, a start motion output and a tool change complete input, I used an arduino to handle the toolchange logic...
