More precisely, it is called Receiver Not Ready by SDLC/HDLC/ADCCP
which is used as the level-2 protocol by X.25 (LAP-B) but in other
situations as well.
BSC calls it WACK, which is much more fun to say, e.g. when narrating
a trace over the phone. Also, ACK0 and ACK1 can be pronounced ack-oh
and ack-eye; just try that with RR-3 or worse I-3-1-P. Although SNRM
is suitably sinister sounding. (An almost Agnewian tongue twister!)
