As you can tell, I haven't written software for pay for a long, long 
time. And if my last msg is a test, I'm not much better at email.

It still seems that with the current code, the first term is true 
because AUTO is in the database and the second term is also true because 
my Nova budget does indeed have the FE_CAN_INVERSION_AUTO bit set. Won't 
this cause the if to evaluate true and erroneously print the error msg?

The caps for my card are:
               FE_CAN_INVERSION_AUTO |
               FE_CAN_FEC_1_2 | FE_CAN_FEC_2_3 | FE_CAN_FEC_3_4 |
               FE_CAN_FEC_5_6 | FE_CAN_FEC_7_8 | FE_CAN_FEC_AUTO |
               FE_CAN_QPSK
