Upgrade to FreePBX 14 from 13 failing

The commands that the module runs are

/etc/init.d/dahdi stop
/etc/init.d/dahdi status
/etc/init.d/dahdi start

The output of status is an exit code retrieved from running echo $? after the command is executed.

When exit code is === 3 then start is run. if exit code is === 0 then dahdi is already running.

Status codes of 0 or 3 are determined by the following code in /etc/init.d/dahdi

    if [ -d /proc/dahdi ]; then
            /usr/sbin/lsdahdi
            RETVAL=0
    else
            RETVAL=3
    fi

This part of the code checks if the folder /proc/dahdi exists. If it does then it executes /usr/sbin/lsdahdi
