Re^2: Threaded RS232 communicationby tobias_hofer (Friar) |

This question is very important. In my case its a integration test system communicating with the target by rs232. What i am sending and receiving are requests for starting test-cases and getting the test-results.To avoid the loss of information i have designed a communication protocol. Thus the communication is going on like a ping-pong game. Only when the communication sequence is done (test-sequence ended completley - recognised by the state machine) I close the rs232 connection. Thus I can be sure that no information is lost. Ok, regarding this test-system its a special case but IMHO having a protocol and a communication desgin is helping a lot to avoid loss of data Best regards! Tobias
