VER < CR>< LF>(There is no space between command)

char[] _mass = new char[]{'V','E','R','CR','LF'};

_serialPort.Write(_mass, 0, _mass.Length);

How TO Create command and send it.

Answer 1

Characters in C# are UTF-16 encoded by default. When you want to communicate over the serial port, you usually use ASCII.

So you need to tell C# which encoding you want and then have it convert it to a byte array. Byte arrays are just bits without an implicit encoding.

byte[] _mass = Encoding.GetEncoding("ASCII").GetBytes("VER\r\n");
_serialPort.Write(_mass, 0, _mass.Length);
