Research direction

Start by reviewing the issue details and the linked Asana report, then locate the driver code that manages pymodbus connections. Reproduce the reconnect behavior with pymodbus 3.3.1 and compare it with 3.2.2. Done means the driver reconnects reliably on the affected version, with a regression test if the project has coverage for this path.
