Automatic Device Recognition
Chapter 1 Introduction 24
Automatic Device Recognition
The Automatic Device Recognition feature allows the Digi Passport unit to
automatically detect and recognize attached devices. The Digi Passport
unit sends a set of automatic detection criteria, including sets of serial
parameters and a probe string (default is < Enter >), and analyzes the
response. If Use detected port title is enabled, the Digi Passport unit
displays the detected OS, device, and port number in the format:
CISCO.Router.port3
Sun.nemo.port5
Automatic Device Recognition also monitors each of the configured serial
ports. If there is a change in the expected response from the device
connected to the serial port, an email message or SNMP trap can be
issued. This means that notifications are sent if the device goes down or is
disconnected for any reason.
To configure the alarm feature, see "Configure Ports" on page 60. For a
further discussion of the automatic detection feature and the settings
involved, see "Configure Automatic Detection" on page 77. To enable
