How is this actually possible? Century or AUTO232 has a memory flaw and
somehow AUTO232 is writing somewhere in the memory which should be
allocated by Century? I don't have AUTO232 myself so I don't fully
know how it's functioning or the protocol/interface it uses but this sounds
very strange to me.
