In order to port an RTOS you need to have additional
stack space to the on chip stack of the 8051.

This means the compiler should use an "external stack
pointer" which uses the external RAM as a stack space.

At the moment only 256 additional bytes are implemented
and not well tested:) as an external stack.

It would be nice to have more than this available as
stack space.

    This is an old one. And I'm wondering if there is anyone
    around (except the anonymous original poster) who is
    interested in this. If not I will close this RFE in a month or so.

    Ok, so if anyone needs this in the future, reopen the request
    or file a new one. For now it's rejected and closed.
