I am trying to find a way to get the CONSOLE status to determine whether
it is ready to receive a character -- from within an assembly language
routine.  It appears that the BIOS function BIOS_CONFUNC with
AH=CHR_STATUS should give me what I need, but I can't find anything
which tells me what value I should be placing into SI as the CID
(internal control table).

Has anybody out there worked with BIOS routines before?  Can you tell
me what the CID should be or where I can find that information?
