推荐答案
如果你写你的字符串港口的编码字节，它们将被正确发送。
这段代码就可以了你！
If you write the encoded bytes of your string to the port, they will be sent correctly. This piece of code will do the trick for you:
string my_str = "isto não está a funcionar! (pt)";
byte[] my_bytes = System.Text.Encoding.UTF8.GetBytes(str);
comPort1.Write(my_bytes, 0, my_bytes.Length);
