Currently I'm tring an telnet client sample written by C# to connet a data acquisition unit, I could connect the server and send the commands, but I always received the same data (I cound't post images, the data is{255,253,3,255,254,1,255251,1}). I also do some research, seems this problem is related telnet protocol/negotiation, but I don’t have any more idea and experience on that what should I do, could anyboday please help to look at it? any suggestion & solution is appreciated.
others, I could directly use the telnet of OS to execute related commands to see the correct data.
