After an embarrassing failure, tests were added to Device::Modbus::RTU::Server. It was not obvious to me how to test this module, so it is detailed here.
The rewritten Device::Modbus distribution is now documented. Well, almost documented: Device::Modbus::RTU and Device::Modbus::TCP are still missing.
A server with the simplest of tasks (returning a constant) was run successfully in a Rasberry Pi.
Today I had a frustrating day at work, which at the end offered an opportunity to test a Device::Modbus client with an industrial temperature controller.
