/************************************
This structure is meant to track the Group-3 FIF for DIS and DTC frames. The FIF is arranged so that the bits are numbered from 1 upward in teh order they are received. Since Modem/Comm behaviour puts received bits in a byte from low to high and the bytes into memory at increasing addresses, the bits need to run in memory from lowest bit of first byte through the highest bit and then on to the next address.
Need to watch out for sudden reversal of the high-low order of bits and of bytes.
The MS C7 compiler puts bit-fields into BYTES from low to high, so this should correspond. Don't change the BYTEs below to WORD as then we'll run into high-low byte flipping nonsense.
If a bit-field crosses a byte boundary we're in trouble.*************************************/
