1) Implement documented but unimplemented read-only option.
2) Allow standard input to be used as the <device> by passing
"-". On some devices, opening the device has side effects.
Allowing standard input can prevent this by using a sequence
of something like:
# Open the device on file descriptor 3
exec 3<> /dev/something
ioctl -d - 0 0 <&3
ioctl -d - 1 0 <&3
dd if=myfile >&3
# Close file descriptor 3
exec 3>&-
