Async read won't return in case the connection is interrupted #58

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Create an async TCP connection to modbus server
2. Disconnected ethernet cable
3. Perform a "read_discrete_inputs"

What is the expected output? What do you see instead?
Expected output is a failed read. Instead I got nothing. The deferred doesn't 
fire.

What version of the product are you using? On what operating system?
pymodbus 0.9.0 on linux and windows.

Note that ModbusClientProtocol.connectionLost has been called.
