IBM 3270 Display Terminal Subsystem control units.As already noted in solution 1 and described in the manual, STX and ETX refer to special characters.Ī large number of devices use the Bisync protocol, some of these are: See Serial Communications on how to do this.
If the sensor is connected to a serial port, you must use serial communication rather than network functions. But that describes the communication via a terminal program (serial connection). That is, STX (ASCII #2 = 'start of text') and ETX (ASCII #3 = 'end of text') are just regular control characters that are used very often for serial communication (as is ASCII #13 = 'carriage return' for signalling the end of a transmission), so these don't qualify for what you called 'special characters'. The reason for this is quite obvious, but it would be easier for you to understand it yourself (I hope) than explaining it. Use (char)STX and (char)ETX, add it to string-only data, and then use .GetBytes to the whole string, to get your bytes. Add STX and ETX as characters, before getting ASCII.
