Module: CHIPCOMMIB

OID (symbolic): CHIPCOMMIB::chipTTYDTR

OID (numeric): 1.3.6.1.4.1.49.2.5.2.1.8

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This value dictates the behavior of the RS-232 Data

Terminal Ready (DTR) signal at the time a session ends

due to a logout, timeout, or shutdown. This is used by

some modems as an indication that they should hangup.

This variable returns notApplicable(3) if the RS-232

port does not have a DTR signal.

What is chipTTYDTR?

This read-write setting controls how the RS-232 Data Terminal Ready (DTR) signal behaves when a session ends via logout, timeout, or shutdown, which some modems use as a hangup cue.
