Trying to google what I am asking for is proving difficult. So if there is something on the forum already, I apologize.
I have to troubleshoot serial communication between 2 devices (ESP-07 and Nextion HMI) I have 2 usb-serial converters plugged into my computer. I would like to have them communicate with each other and log "who said what" on my pc.
I am handy with c# so if there isnt something, maybe I can whip up something.
