# PowerShell script to disable Windows power management on all currently connected serial ports, including USB adapters
# In simpler terms, it prevents Windows from turning off connected serial devices to save power.
# Equivalent to right-clicking on a serial port device in Device Manager > Properties > "Power Management" Tab > Unchecking "Allow the computer to turn off this device to save power."

# To run it you have a few options:

# .\SerialPowerMgmt.ps1 -Enable - this would enable power management (default)
# .\SerialPowerMgmt.ps1 -Disable - this would disable power management
# .\SerialPowerMgmt.ps1 -Disable -DryRun - just for testing, no change is done
