Since it had an oldish FW on it, first thing I did was bringing it up to the latest available: DMCP 3.22 + DM42 3.19 (split update).
I have noticed a couple of things about the fonts:
- The 0 (zero) character is now slashed rather than dotted as in most of the online material.
- Using Shift-F5 a third font is available: it's not mentioned in the manual, and looks like a heavier stroke (bold) version of the non-HP one.
Also, I really love dotted zeros: my go-to fonts for code editing are JetBrains Mono and Source Code Pro.
Form a quick look in the GitHub repo, it would seem the only way to achieve this font change is directly patching the closed source DMCP binary.
This might prove to be note really straightforward - I would imagine there's an hash or checksum in the image to make sure it's not corrupted before flash - I'm not afraid of a little assembly code, but I have no real intention to reverse engineer it.
Maybe I'm wrong and an easier method is available. Is there any way to customize them?
