How to detect / diagnose the serial pin configuration of a RS232 device

[nodecentral]

Hi, i've started to use Serial-Comm-Tester and it's working very well. (thanks so much for sharing)

I have it running on WIndows 10, with a USB to Serial device plugged in

One thing I'd like to do is connect a RS232 device to it, and detect what pin configuration it's using to communicate ?

Is that possible to do ? Can Serial-Comm-Tester tell me which pin is being used for what e.g. TX and GND being the main ones ?

When it comes to RX I assume that would not be possible to detect , unless you know anything ?)
