USL-5P Serial Port access

Hello Port-sh3,

Today I became the proud owner of a Landisk USL-5P[1]!

The install notes[2] state that the device does not have an external
serial port and that "you will have to make yourself a special
cable to access it."

I opened the device and inspected the PCB[3][4] but there were no
obvious headers for a serial port connection.

Does anyone have any more information about using a serial cable with
this device?

Thanks in advance,
Travis Paul
