[50G] Question

[Tugdual]

One more (very) naive question: what if I erase L226, L227 and or L229?
I was shocked to see I could do it ! Of course it is on EEPROM and in a sense it is good to have a choice to do whatever you want with your EEPROM but what is the alternative if you erase it?

Another thing I discovered is that any time the 50g is resetted (even hot reset) at least two essential things are lost: KEYTIME and Contrast/ So I created a program called Settings that sets back the Keytime to 500 and I will extend to whatever flag is lost (apparently none) but then I still need to set the contrast with ON+ or ON-.
1. is it possible to set contrast programmatically?
2. is there a better way to save/restore ones settings?
