Hi friends, In our application, we get an error, "frame error". Can somebody inform me about 'frame error'? In our application, we use 232 ports to communicate between machines(serial communication).One machine (say pc) transfers data(8 bit plus start and end bits, totaly 10 bits per sending) and the other machine receives the data. When we open one extra com port, we get the 'frame error'. Why do I get this error? And how can I fix this error? Any suggestions will be appreciated.
