May I capture and see RS232 traffic with Wireshark?

0

Hi everybody there.

May I capture and analize traffic sent and received on an RS-232 interface (COM1 or COM2) of a PC, i.e. the traffic for a Console port of a Router, or a dialog with and old PLC, etc?

Of course, RAW data would be OK!

In the list of interfaces & protocols, I can't find "RS-232" at all...

Tnx in adv to you all!

Currently this can't be done directly from Wireshark.

See this question for other solutions: https://ask.wireshark.org/questions/23243/how-do-you-capture-serial-com-communications

There is also some development work being undertaken to allow external capturing facilities to be integrated into Wireshark. Look for extcap, and see here and here.
