capture serial data using USBPcap


Few weeks ago I've made some test: Using USBPcap and I've used to capture RS232 and RS422 data. I've used RS to USB convertor.

  • For RS232, the data was textual. Each row that I've seen on the terminal was as single frame on the wireshark.
  • For RS422, the data was binary. Each byte that was sent, was as single frame in the wireshark.

Any idea how to solve the issue for the RS422 so that the whole message would be as single frame?

(If I'm not wrong for RS422->USB I've used the ATEN adapter. No idea which one was used for the RS232).
