I had previously given some wrong information (so,... what's new?)

You CAN do /B copies TO a device (I shoulda remembered; I used to have to
do that to load certain fonts into laserjets)

But you cannot, without appropriate additional software, do /B copies
FROM a device.

In the case of DOS 6.22, the message "Cannot do binary reads from a
device"
is at offset 970F in COMMAND.COM
