Very happy to announce ! I found a hole at the "black_box" SX88 , operating system . I had need to discover a way to do a "cron" , like all others STB's , linux based .
My systems , started and stop , by a mechanical clock system , twice a day (with separate options , from work days and week_end days . For starting , no problems , but an abrupt disconnection (power-off) , may alter the status of the internal OS . Now I am safe to do the job , and tasks , like my own backup or shutdown , are programmed when I want . I'm using the last OS - rev. . Bye
