Brett,
Looks interesting.
A few things you may have considered for implementation:
Using a FIFO buffer on messages from the PC/E-net side to serial as
there can be more messages than the RS232 can cope with when a 'big'
device updates its status (like n Netiom's). Add some inteliigence to
drop messages if queued for too long (though I'm sure this would be
considered as bad form!).
Keep a list of the serial attached devices and don't send targetted
messages to non existent devices. This of course assumes the serial
isn't 1:1 but multidrop (RS485).
