This is not a fatal flaw. There is nothing in the definition of RS232
or the serialinterface that guarantees you an error free data stream -
not on that protocol level. You are facing loss of Ethernet packages
on the network as well.
Problems start only when you make wrong assumptions.
Best regards,
