    516516* PCN: All Gateworks GW16130 Iridium Satellite Modems manufactured after 07/08/2020 will have the CBUS0 (SAT_ON) pin configured through the EEPROM to always drive a logic high to enable the modem by default at power-up. It was previously driven low by default.
    517517* If it is desired to have the modem GPIO controlled (rather than through the EEPROM), one can use the instructions on the following wiki page [http://trac.gateworks.com/wiki/expansion/gw16130 GW16130 Wiki Page]. This wiki will explain how to reconfigure CBUS0 to be a GPIO and use the Linux kernel gpiolib (/sys/class/gpio) or a libftdi function to enable the modem through a GPIO. Setting the GPIO to a logic high (it will be logic low and disabled by default).
