People associate things in patterns.  Numbers, odd/even
permutations, etc. but they definitely not use the number 0.

A global LAN_MODE variable internal to MINT, similar to the
ST_ESCC variable introduced a while back.

OK, call it an internal kernel variable, which is definitely
something an XDD can read, after it becomes an integral part of
the kernel, once it is loaded.

LAN_MODE=[lan|serial]


Since an internal kernel variable tells the driver which port to
use, no application can control it, so there is no problem

The variable could easily be ignored by the kernel, if the proper
XDD was not loaded.
