I have no even information about the hardware or software.. All I´m doing is for my career's final project but the protocol is used by a domotic company. I dont work for this company so it´s difficult to me to obtain many information. I have only the description for protocol messages. They have an aplication that capture rs485 and can save it in file (but no in pcap file format) so I think I could use this saved files in wireshark using wiretap. Is there any information about development with wiretap? I was looking for it, but I haven't found anything. Sorry for my english.

But now I would like (if possible) to capture packets in real time. I think it´s not possible to capture live data from rs485 using wireshark directly but if anyone have worked in it I'll be grateful for any help.Ultimately, Wireshark's ability to capture from a traffic source is dependent on libpcap/WinPcap's ability to capture from it, which is dependent on the OS on which you're capturing and/or the hardware used for the capturing. Modern versions of libpcap (for UN*X systems) and WinPcap (for Windows) support adding modules to handle various types of capture hardware and software (although they're modules compiled into the libpcap or WinPcap library, not plug-in modules loaded at run time). On what operating system or operating systems do you want to do the capturing? What software does it have to support RS-485? What sort of hardware do you have to connect to the RS-485-based network? An RS-485-to-USB converter, as you mention, or some other form of hardware (such as a serial transceiver)? Do you want to capture traffic on an RS-485-based network that's neither sent to nor from the machine doing the capturing ("third-party" capture), or do you just want to capture traffic sent to or from your machine?
