RS485 CDU Display Font Issue

Hello people!

I have an issue getting my 3.5 tft to display the correct font over rs485. I have a correctly wired rs485 network using max487 chips as displayed by Hans and many others.

All libraries and dcs bios are fully updated.

The font has been corrected for the A10 via the glcdfont file under adafruit_GFX_Library.

Please also note that the font and cdu work perfectly via serial using the following sketch.

/*

Tell DCS-BIOS to use a serial connection and use the default Arduino Serial

library. This will work on the vast majority of Arduino-compatible boards,

but you can get corrupted data if you have too many or too slow outputs

(e.g. when you have multiple character displays), because the receive

buffer can fill up if the sketch spends too much time updating them.

If you can, use the IRQ Serial connection instead.

So I then converted the same sketch to RS485 and uploaded it to the cdu mega slave 1.

Like I said, the font doesn't display correctly at all, as if I didn't update the library glcdfont.c font. It's as if the RS485 network doesn't even look at the font in the library. Weird problem, thank you for any help.

glcdfont.c.txt

+++++UPDATE+++++

I got a little closer to getting this working via RS485.

I used the following sketch to get the font to display correctly for about 10 seconds but then the cdu display starts to display odd characters and won't stop.
