Automatic detection - Enable or disable automatic detection of devices
Use detected port title - Enable if you want the Digi CM unit to automatically use the results of
the detection mechanism to populate the port title. Disable if you want the default port title. If
you choose Disable, you can still use the alarm feature.
Port title - Manually entered or automatically populated title of the port.
The Digi CM unit allows access to a port by using only the number of the port title, making it
unnecessary to know the serial port number.
The default is set to “Port Title xx” with xx being the port number.
Probe string - The probe string is an ASCII string that is sent to the device.
Special characters are coded in hexadecimal values like:
CR \x0d
LF \x0a
ESC \x1B
Examples are:
Parse string output
root\x0d\x0a root<CR><LF>
\x1Btest\x0d <ESC>test<CR>
\x1B test\x0d <ESC><Space>test<CR>
\x1b\x20test\x0D <ESC><Space>test<CR>
\x1B\x20\x74\x65\x73\x74\x0d <ESC><Space>test<CR>
Detected OS - Displays the result of the Active or Passive detection process.
Device detection method - If Active is selected a probe string is periodically sent to the device
and the response is analyzed. If Passive is selected, the port logging is parsed to determine the
device name and the OS.
Detection initiation - Active only if automatic detection is Enabled. Periodically or If new device
is detected are the choices in the drop down menu. If Periodically is selected, the probe string is
sent once every n minutes to the device while no connection is active to the serial port. When a
new device is detected is selected, the probe string is only sent if a change on the DSR signal on
the serial port is detected. Normally a device will activate the DSR signal if the serial port
becomes active.
Detection delay - The delay before the first active detect process is started and between active
detections.
