                  I want to know if I put these in my code, does computer send any kind of signal to the device?

                  SerialPort myport = new SerialPort("COM1");
                  myport.DtrEnable = true;
                  myport.RtsEnable = true;

                  我需要在特定引脚上向设备发送信号.我知道 Dtr 和 Rts 使用引脚 4 和 7.所以当我编写上面的代码时,我的计算机会在引脚 4 和 7 上发送信号吗?还是有一种简单的方法可以在特定引脚上发送信号?

                  I'm required to send a signal on specific pins to the device. As I know Dtr and Rts use pins 4 and 7. So when I write the code above, will my computer send a signal on pins 4 and 7? Or is there a simple way to send a signal on a specific pin?



                  In theory: Yes. Whatever you have connected to your serial port will see something. It won't be data, but if it is checking its pin states, it will know that you have done something.

                  在实践中:也许.能否准确检测这些引脚状态在很大程度上取决于所使用的电缆.这是最近的帖子 讨论了与这些引脚状态相关的电缆问题.

                  In practice: Maybe. Being able to accurately detect these pin states is heavily dependent on the cable being used. Here is a recent post that goes over the cable related issues with these pin states.
