如何通过USB连接两台Windows计算机以在其虚拟串行端口之间进行通信？

Question

What is needed for the physical USB connection between two Windows computers for communication between their virtual serial ports? Should I use USB/serial adapters?

I am building a .NET terminal app on Windows 10 Pro computer that must use a virtual serial port for communication through a USB connection to the virtual serial COM port at a Windows 7 Pro computer that is running the terminal app on .NET.

The terminal app is the PortChat example app from MSDN's serial port documentation .

PURPOSE: I need to test a serial communication .NET app on Windows 10 that will eventually communicate with an embedded STM that is presently unavailable .

Answer 1

You need two usb/Serial adapters and connect them to each computer. Then connect those two serial interfaces together with a Null Modem Cable .
