Answer 1

you can use the System.IO.Ports.SerialPort class to use the serial port in C#. The data received by the SerialPort class is of byte type and can be converted to string type.

According to your description, each data frame you receive has a fixed length. You can add a processing of parsing the data frame to the receiving function. For example, when data of a certain length is received, it is converted into a data frame, and the extra string On to the next analysis. If the data is not of fixed length, a terminator can be added to the data frame to determine.

The data frames of serial communication are defined according to their actual needs, and the format of the data frames is uncertain, so the parsing process needs to be completed by yourself.
