no equivalent I can see with regards to non-console reader devices an=
d I'm kind of stumped on how it works. Does anybody have experience with th= is and can provide some clues? I've tried just implementing something assum= ing the RDR: is polled, but it doesn't seem to work. Thoughts?
I've managed to get it working as intended. But if anyone *wants* to add any additional help (possibly for others) feel free.
Note: if you are going to add non-standard JMPs to the BIOS vectors, you may not need iobyte as your program(s) can just make BIOS calls for RDR:/PUN: (AUX:) status. Of course, those programs become non-standard then (not very portable to other CP/Mimplementations). Even using iobyte, that limits the platforms your programs can run on (many did not implement iobyte).

I dug around my floppy disk images and found where I once did this for CP/M-68K. Pretty much the same way.
This file is very out of date!
It is the same as the very first version from 2014:
