Using the Serial Port on KBL Intel NUC
======================================
You can enable the serial console on the
`KBL Intel NUC <https://www.amazon.com/Intel-Business-Mini-Technology-BLKNUC7i7DNH1E/dp/B07CCQ8V4R>`_
(NUC7i7DNH). The KBL Intel NUC has a serial port header you can
expose with a serial DB9 header cable. (The Intel NUC has a punch out hole for
mounting the serial connector.)

<https://www.amazon.com/dp/B07BV1W6N8/ref=cm_sw_r_cp_ep_dp_wYm0BbABD5AK6>`_
such a cable or you can build it yourself;
refer to the `KBL Intel NUC product specification
<https://www.intel.com/content/dam/support/us/en/documents/mini-pcs/nuc-kits/NUC7i7DN_TechProdSpec.pdf>`_
as shown below:

<https://www.amazon.com/dp/B07BV1W6N8/ref=cm_sw_r_cp_ep_dp_wYm0BbABD5AK6>`_
You'll also need an `RS232 DB9 female to USB cable
<https://www.amazon.com/Adapter-Chipset-CableCreation-Converter-Register/dp/B0769DVQM1>`_,
or an `RS232 DB9 female/female (NULL modem) cross-over cable
<https://www.amazon.com/SF-Cable-Null-Modem-RS232/dp/B006W0I3BA>`_
to connect to your host system.
Note that If you want to use the RS232 DB9 female/female cable, choose
the **cross-over** type rather than **straight-through** type.
