I was looking for that all day.  Glad you found it.

No, it's rock solid on the CBM platform, so I expect it would be the 
same on the Coco.

Most folks appreciate the idea of getting an IRQ when a packet arrives.  
In most newer switched Ethernet environments, you won't see any packets 
until one comes for you.  Thus, you can safely do other stuff and then 
an IRQ will mean there is actual data for you.
