Using UART
#7
As Xalius mentioned, voltage matters! Standard RS232 serial could be as much as -15 to +15 (30v full swing) as opposed to the 3.3v/TTL that is required by the A64/RK3399 used in the Pinebook/Pinebook Pro. Meaning depending on how true that cable is to the spec, at minimum it could fry the RX/TX GPIO pins, and possibly fry the CPU completely.

Information on the pinout, baud rate, etc is here on the wiki.
