Does matlab support RS485 support via com port? If so, I can't find any guide to how it works.
I have tried this code, but it does not work. If I send the numbers through realterm n RS485, it works fine.
s = serial('COM3','BaudRate',38400);
set(s,'StopBits',1);
set(s,'DataBits',8);
fopen(s);
fprintf(s,'2 7 2 2 255 255 255 248');
fwrite(s,'2 7 2 2 255 255 255 248');
fclose(s)
