# 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
You can also read [my blog post][blog] for more information about this.
