QDOS?

Dunno, I don't have quite such old versions :-)  My old copy of "The
MS-DOS Bible" says "every version" -- it means 3.30 and older --
disallows binary reads from devices.  The same message is at 5254 in
MS-DOS 3.30 (ditto in PC-DOS 3.30), at 4CA0 in 3.21, and 4CCC in
IBM-DOS 4.01 (from a Compaq).  I can't read my MS-DOS 2.10 and 2.11
disks on the hardware I have here.  "Binary reads from a device are not
allowed" is the message at 8753 in DR-DOS 3.41.

All the ones that I could boot (ie all but 2.10/2.11) print the message
and then exit when you try COPY /B CON: dummy .
