Start by tracing the reported call path through socs/agents/vantagepro2/agent.py:138 and socs/agents/vantagepro2/drivers.py:362 and :94, then compare it with the serial write failure in the log. Reproduce or characterize the Vantage Pro2 I/O failure and define completion as acquisition no longer crashing on the reported condition.
