“S” CODES
“S” codes appear in response to a “STATUS?” query. There are two “S” codes for the RFL DA-91I
when operated in a T1 or E1 system: S1 and S2. Like the “P” code, this number is displayed in both
decimal and binary form.
A typical response to a “STATUS?” query looks like this:
* OK
CHANNEL CARD 3, TYPE 126
S01 = 3 (B00000011)
S02 = 15 (B00001111);
