Display Hex in PuTTY for Serial

Question

Does anyone know if there is a way to get PuTTY to show the hex values of what it's receiving over a serial connection instead of characters?

Solution

In initial screen

Session | Logging

Select All session output, then select save file.

After saving the file, use any hex editor to see the result.

The question is tagged and specifically mentions serial port communication.

In raw mode, it still doesn’t print non-printing characters. It also seems not to put them in clipboard when copying/pasting.

This also helped for me when Putty was not showing anything at all on the screen because of blank values (i.e. 0x01 which is "start of heading" in ascii. )

All 0x00 were missing for me (Putty 0.67 on Win10, visualized with fhred 1.7.1)
