BCPVAL

1 = BCP(4) or TA(0)

Note 1: Bit 6 of the Interrogation will be interpreted as BCP(4) if (EXTFMT = 0);

if (EXTFMT = 1), the BCP (4) output will be 0 and bit 6 will be interpreted as TA(0).

Note 2: (RIRVAL = 0) (presumably because of bad Interrogation length or received Litton coding errors detected by the

modem), bad received parity in bit 31 of the Interrogation or wrong Interrogation length will both cause the

Interrogation to be rejected and will set BCPVAL = 0.
