# T-937/M Serial Captures

These are Wireshark capture files of the oven communicating with its control application.
The data has been captured as USB packet traces using CH341 and PL2303 USB-to-Serial adapters.
You probably want to load the Wireshark dissectors from the dissector directory to look at it:

    wireshark -Xlua_script:ch340.lua,pl2303.lua,t937.lua

## Capturing USB-to-Serial communications on Windows

- install Wireshark with USBPcap
  - make sure you [have `USBPcapCMD.exe` in your extcap directory][usbpcapcmd]
- set up capture options
  - disable "Capture from all devices connected"
  - disable "Capture from newly connected devices"
  - enable Inject already connected devices' descriptors..."
  - enable only the USB-to-Serial device
- start capturing
- connect from Pb-Free.exe
