Subject: how to detect whether a laptop is docked

Dear Cygwin Users:

I am looking for a method by which I can determine within a shell script 
whether my laptop is docked or not. Google provided some answers for Linux 
and Windows users, but the several ways I tried did not work out.

One Windows solution * provided a VB script that accessed a registry variable ‡,
but my registry value remains the same whether or not I'm docked. 

The Linux solutions required either a file I don't have (/var/run/stab) or a tool
that I don't have and couldn't find in a Cygwin search (acpid or lsusb).

* https://www.autoitscript.com/forum/topic/147332-how-do-you-detect-a-docking-station/
‡ /proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/IDConfigDB/CurrentDockInfo/DockingState
