Franson also makes serial port splitter software, which opens up virtual COM ports on your PC, which your software connects to and the other software connects to. This is not free.
使用电压兼容的 USB 转串行加密狗，它将充当新的 COM 端口。使用绕线连接 RX、TX 和 GND 连接。在 PC 上使用 TeraTerm 打开并查看新的 COM 端口。 RX 和 TX 都可以工作；尽管两者都在传输时发生冲突可能会产生垃圾。
请注意，通过执行此操作，您的 PC 地线将通过 USB 转串口适配器上的 USB 地线连接到硬件板的地线。对于简单的开发任务来说，这通常是可以的。
Use a voltage compatible USB-to-serial dongle which will act as a new COM port. Use wire-wrap wires to splice into the RX, TX, and GND connections. Use TeraTerm on the PC to open and view the new COM port. Both RX and TX will work; although collisions when both are transmitting will likely yield garbage.
Note that by doing this, your PC's ground will be connected to the hardware board's ground, through the USB ground on the USB-to-serial dongle. This is usually OK for simple development tasks.

是的，有几种方法可以在软件中做到这一点。我使用这个免费软件：

Franson 还制作串行端口分配器软件，该软件可在您的 PC 上打开虚拟 COM 端口，您的软件连接到该端口，其他软件也连接到该端口。这不是免费的。
Yes, there are a few ways of doing this in software. I use this free software:

我只知道使用硬件 RS232-Spy 这种方式。

看起来不错！
I just know this way using hardware RS232-Spy.

Good look!
