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.
