I don't think so, because the commands that are failing from within
chg-manual work if I type them in eg:

SRV# echo "insert tape into slot $1 and press return" >/dev/tty
insert tape into slot  and press return
SRV# read ANSWER </dev/tty

I agree, however from the command line I have full access:

SRV# mt -f /dev/nsa0 rewind

SRV# dd if=/dev/nsa0 bs=32k
