Are you implementing the input storage as a circular buffer ?
If so, then perhaps the problem isn't as big as it seems, as you may choose
to put the input chars to a 'putbuf()' function - which internally decides
where to put the data (skipping registers etc)...  similarly, your on-board
processes can 'getbuf()' for the next buffer char - if any.

Cheers

To Andy..
yes, Andy, that would work, if there were no register blocks in between!

An example:
RAM Startadress:0x20 then 96 bytes of free memory, then follows a
register block from 0x80 to 0x9F with processor registers, after that
another chunk of free mem until 0xEF ..etc.
So the memory is interrupted by these processor-own register blocks...
I guess that is the problem! Or am I wrong?
Alf
