[comp.os.os9] os9 trap question

edstrom@elmer.hsc.ucalgary.ca (John Edstrom) (01/15/91)

I am trying to write a device driver in assemnler.  There is an instruction
called 'os9' which generates a trap.  I can't find anything in my documentaion
that explains what the valid arguments to the trap are and what information
needs to be in which registers for each arguement.

Can somebody either send me a table of such information if they have it
or let me know where I can find it in the documents (standard Professional
OS-9 operating manuals, vol I & II).

Thanks in advance.
