The serial library probably internally uses null terminated strings so taking your first 0 as end of the string.
I'll try to check, maybe I could add function to send single byte...

No code change can be done by Hidmacros anymore - or no code change by me. Sorry.

The answer is already here above, but you need to know lua to use luamacros.

I don't think it's possible. The Fn is more on hardware level to add some extra function to the key

Your game is probably reading the keyboard "directly", at low level. Hidmacros can't block such direct access

You can hook as many keyboards as you want in 1 script. Just call lmc_set_handler with different keyboard id - see e.g. https://github.com/me2d13/luamacros/blo ... c.lua#L244

With lmc_set_handler used with 2 arguments you're assigning callback function for whole device - so all keys will be blocked. And your script is handling only the case with numlock off. If you need to script only individual keys, add key number as agrument to lmc_set_handler. See https://github.com/...

Did you follow https://github.com/me2d13/luamacros/blo ... evGuide.md?
What's your free pascal version, 32 or 64 bit?
Also you may try the most recent branch which was FSXX poc, it's for 64bit FPC compiler https://github.com/me2d13/luamacros/tree/64bit

No, there's even code in LuaMacros forcing one instance only. The software uses some dirty hacks to block original key in active application and this is done via global shared memory between active application and luamacros. Having 2 instances would clash with this shared memory even if one of them ...

Try to run with -k parameter.
I don't remember exactly - it even does what you need (stop blocking original key) or it doesn't read keyboard completely (so it can't be used as macro trigger)
