S-Register Commands

DIVA T/A ISDN Modem Reference Guide ◆ Page 58

S25 Data Terminal Ready Detection Delay. Specifies the duration that the Data

Terminal Ready (DTR) status must either be raised or dropped before being

recognized by the DIVAT/A. This delay helps ensure that the DIVAT/A does not

interpret a random glitch as a DTR raise or drop.

This register affects the AT&Dn command, which controls interpretation of the Data

Terminal Ready (DTR) input (see page37). Essentially, detection by AT&Dn will be

delayed according to the S25 register setting.

Range: 0-255, in tenths of a second. For example, if set to 5, the duration is five-tenths

of a second, or 50 milliseconds.

Default: 0. Type: S torable.
