NUT apc_modbus word-order bug proof — source bit hypothesis test (disproved)

	#!/usr/bin/env python3
	"""Bug 4 — Test: Does setting SOURCE_RJ45_PORT bit fix OutletCommand writes?

	This script bypasses the NUT driver and sends a raw Modbus write to register
	1538 (OutletCommand_BF) with the SOURCE_RJ45_PORT bit (bit 14) set.

	Command: load.on targeting MOG (Main Outlet Group)
	- Without source bit: 0x0102 = CMD_OUTPUT_ON \| TARGET_MOG
	- With source bit: 0x4102 = CMD_OUTPUT_ON \| TARGET_MOG \| SOURCE_RJ45_PORT
