Not anymore - as has already been noted it was removed from the standard 
Oberon-07 RISC compiler.

Yes.  I looked at the old OSG code, not sure why it wasn't set in 
OSG.Header as I suggested just now.

Wow. Ok. Just make sure what you are sending is exactly what is 
required, ie lengths and addresses correct, words in littleendian 
binary.  The serial bootloader has no error checking, as you can see 
from BootLoad.Mod.  It might still "kinda" work, but not work correctly, 
when bogus data is received.
