S0 Number of Rings Until Answer

Unit: 1 ring

Range: 0–255

Default: 1

Sets the number of rings the TA waits for before it answers and begins its connect sequence. S0=0 turns off the ability to automatically answer a call. S0=1 causes the TA to automatically answer after 1 ring. Note that if the S0 value is set too high, the calling device may time out before the TA answers the call. For autoanswer, S0 must have a nonzero value, DTR must be high (&D command), and the TA must be offline.

S1 Ring Count Unit: 1 ring Range: 0–255 Default: 0

Counts the number of rings that have occurred, up to a maximum of 255. It is a read-only register and is seldom, if ever, used in typical operation.

S2 Escape Character Unit: Decimal ASCII code Range: 0–127

Default: 43 (+)
