STM8S103F3P6 dual machine communication [Copy link]

I would like to ask, has anyone used STM8S103F3P6 to make two-machine serial communication? (PD5, PD6). I tried it, but it seems that the serial port cannot communicate with two machines? The RXD and TXD of the two machines are directly connected, but no data is received?

First use the computer to adjust one side, and then adjust both together. You can connect the lines in parallel and observe them on the computer.

Yes, please communicate with the computer first to see if it can communicate normally.
