Previously, I was confused that the Super Terminal that comes with windows could not send and receive at commands from Nokia mobile phones, so I always thought that Nokia mobile phones could not use AT commands.
Today, I used serial monitor to re-monitor the communication process of a play-on mobile phone. I found that I can send and receive at commands as long as I set RTS = on and DTR = on. When a Super Terminal is connected, only the DTR is set to on, but the RTS is not. This is why the connection is unavailable.
In addition, when sending and receiving the fbus command, you need to set the options of RTS = off and DTR = off. Haha, it seems that the serial port is quite fun :)
I am free to write a complete and easy-to-use serial port tool.
