How to send to comport?

Question

C++ / C#

you need to send this array of bytes to the computer port and get an answer byte[] ak = { 00, 03, 01, 00, 00,0C, RCR };
swears at 0C and RCR that these are not bytes. can you tell me how to do this??? and how then to accept the answer from MK? And how to see if the bytes reach the comport?

Answer 1

RCR is definitely not a byte, it's not even a hexadecimal number. 0C change to 0x0C. To work with a COM port, use the SerialPort class https://docs.microsoft.com/en-us/dotnet/api/system...
