In my application my system which I will connect will send data continously to serial port. As soon as I connect the system I will read 15 bytes and this bytes is sufficient for me for analysis. After I read data I will flush the serial buffer so that data shouldnt be mixed with data sent by next system.
I read successfully first time then second t ime I get first error then 3 is successful read then 4th again error and go on.
1. The connection for the given session has been lost. or
2. IO ERROR
