Sniff Session
A sniff session enables multiple users to access a single serial port for viewing
the data stream. Anyone that is registered for a sniff session can access a
specific serial port even if someone else is using the port. The Digi CM
supports multiple concurrent sniff sessions.
There are four options for a Sniff Session mode, disabled, input, output, and
both. You can configure the sniff session modes on a per-port basis from the
Serial port configuration page.
Enable/Disable sniff mode
• Disabled -The sniff mode is disabled and no one can enter a sniff
session after the first person is logged on.
• Enabled - - Allows everyone with access the following options while in
sniff mode:
Sniff session display mode
• server output - View all data to a serial port from a remote connection
• user input - View all data from a serial port to a remote connection
• both - See all data transmitted or received through a serial port
Display data direction arrows
• Enable/Disable - displays arrows to indicate direction of data to or from
the server. When accessing the port as a second user the global "Port
escape menu" will be displayed. See "Port Escape Menu" on page 16.
