Bit 0 = AUPC Communication Error
Bits 1-2 = Eb/No Status
0 = Eb/No is Invalid
1 = Eb/No is Valid
2 = Eb/No is Smaller Than Indicated Value
3 = Eb/No is Larger Than Indicated Value
Unsigned Binary Value Decimal Point Implied
Note: The following byte applies only if an asynchronous
interface card, IDR or IBS interface card is installed, and
the AUPC option is installed and the AUPC is enabled. If
not, ignore this byte.
0 = Daughter Card OK
1 = Daughter Card Faulted
The following byte applies only if an IDR or IBS interface
card is installed and the modem is in IDR mode. If not,
ignore this byte.
