On a windows PC I'd like to be able to find an approach to see incoming data on a serial port, as it comes in (i.e. rather than logging to a file and then converting and viewing the file after the fact).
I have been using PuTTY with a font (Compendium Arcana) that displays characters as hex values, but values that equate to ASCII non-printing hex values do not show (e.g. space still shows as a space, and ASCII SOH [0x01h] does not display at all)
Is it possible to make PuTTY, or any other terminal emulator, display these characters as they arrive?
PS: I could probably live with spaces being displayed, or indeed any actual character being displayed, rather than nothing being displayed. this would mean I could at least tell the difference between one character and another.
