Though this might be useful in few situations, I do not plan to put it into
the BIOS kernel (at least not in the next time), since it would use up to much memory. If the kernel may run in protected mode somewhere in the future,
we might add such things... However, someone could write an external
device driver to provide such  special devices ...

Yes, actually an  !  operator and special groups in CONFIG.SYS have 
both been under my consideration.  (And I also had the  !  char in mind -
appears quite a good choice ;-)  ) Both was quite easy to implement, 
but at present there are more important things to do first, e.g. improving
the compression algorithm, adding MS-DOS style boot menus etc., and
other things to improve interoperability with other OSes. But, they are
on my todo list...
I won t stop anyone from implementing new features to IBMBIO.COM,
but my current sources have changed so much compared to the original
ones, that I might not be able to put your patches in, if they are based on old sources. However, I actually hope this will change soon, and things will be moved into the  official  BIOS kernel... 

 Matthias

PS: There are still several open questions (see at the end of the 
README.TXT file of IBMBIOA3.ZIP), and I would like to receive your
reports...
