5-2 S-REGISTERS

S0 – Number of Ring Characters before Modem engages

Where the value of S0 = 0, automatic answering is switched OFF and the modem

does not go on-line. Where the value of S0 = 1, the modem goes on-line at the ﬁrst

ring sign, or character.

Range: 0-2 ringing characters; factory setting: 0

S1 – Ring Character Counter

The value of this Register is increased by 1 with each ring character which is rec-

ognized. It is deleted when pauses exceed 8 sec.

Range: 0-255 ring characters; factory setting: 0

S2 – Esc Sequence Character

ASCII value of the character deﬁned as the Esc sequence, to change from data mode to

command mode. The Esc sequence is switched off where this value exceeds 127.

Range: 0-255; factory setting: 43 (ASCII+, “plus” sign)

S3 – Carriage Return Character

ASCII value of the Carriage Return character (<CR>Carriage Return) ends the

command lines and modem messages.

Range: 0-127; factory setting: 13 (ASCII CR, Carriage Return)
