Now add “/usr/bin/devterm-a06-gearbox -s 6” to /etc/rc.local so it runs at boot.
Don’t forget the “sleep 15” command above it.
cpi@clockworkpi-a06:~$ sudo vim /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sleep 15
/usr/bin/devterm-a06-gearbox -s 6
