5.9. Armadillo-IoT RS232C Add-on Module RS00
The Armadillo-IoT RS232C Add-on Module RS00 (hereafter referred to as the RS232C add-on module) has one RS232C
level serial port. Since the device driver of the serial port of the RS232C add-on module is implemented as a TTY device,
it can be controlled from the TTY device file.
