Hello Louis,
simply type:
echo BB-UART4 /sys/devices/bone_capemgr.9/slots
Why this variable?
For control type:
cat /sys/devices/bone_capemgr.9/slots

You probably have a bone_capemgr.8 instead of a .9. Have a look. Or just try
using .8 instead.

Hello Louis,

$SLOTS is an environmental variable pointing to
/sys/devices/bone_capemgr.9/slots
I'm not sure how I can cat $SLOTS, see what I expect, but then not be
able to
