It's not just laptops and appliance boards - even ATX sized PC
motherboards have been made with no com ports for a long time,
for example the Intel DH67CL from 2011.  The specifications at

  https://ark.intel.com/content/www/us/en/ark/products/50101/intel-desktop-board-dh67cl.html

say

  # of Serial Ports:  0
  Serial Port via Internal Header: No

and when booting NetBSD on one, the dmesg output contains no "com" entry.
