Tested with Wireshark on Windows (mostly working). To use extcap, run Wireshark and go to the About-dialog. Find a tab located there named "Folders". Locate the extcap search path. Copy the mstpcap.exe to that folder, which may not exist. Restart Wireshark, and look for "BACnet MS/TP on COMx" interfaces. Configure the interface to change baud rate. Capture directly from the interface.
