These kermrc files are meant to be used with ckermit as initialization scripts.  They are named according to which interface they communicate with.  They can be used to initialize kermit like this :

kermit -y ~/LUMINARY.kermrc

ctrl-\ then 'c' then typing quit will exit kermit.

With the Kontron FC14 live image the ports should map like this :

ttyS4  : OEM628      : COM1 : 
ttyS5  : TOUCHSCREEN : COM2 : 
ttyS6  : DGPS        : COM3 : -->ttyS7
ttyS7  : LIGHTBAR    : COM4 : -->ttyS6
ttyS8  : COM2        : COM5 : -->ttyS9
ttyS9  : NOT PRESENT : COM6 : -->ttyS8
ttyS10 : LUMINARY    : COM7 : 
ttyS11 : 2NDDISPLAY  : COM8 :
