Hi Mark,

I have more question about driver : 
1. Why is rx and tx_callback registerd two times ( in npe_init and npe_start) 
- I try to add driver to eCos  multithread application.
2. NPE Mh is initialized in interrupt mode but in npe_poll is checked for 
messages from the NPE. Is that correct ?
 
Best Regards,
Jerzy
