Operation

9.1.2. Passive Mode

Passive Mode Ports function the same as Any-to-Any Mode Ports, but do not allow

access to command mode. A Passive Mode Port can be connected to other serial

ports, but cannot enter command mode, and therefore cannot be used to define

parameters, display status, or invoke commands to connect ports or control power

switching. The Passive Mode is the default at Serial Ports 2 and above.

Passive Mode Ports can be connected by accessing command mode from a free Any-

to-Any or Modem Mode Port, and invoking the Third Party Connect or Resident Connect

Command as described in Section 9.1.1.1. Passive Mode ports will not buffer data,

except during baud rate conversion.

functions,thePassiveModeisnotavailableatPort1(theSetUpPort)orthe

NetworkPort.

9.1.3. Buffer Mode

The Buffer Mode allows collection of data from various devices without the requirement

that all devices use the same communication parameters. In addition, Buffer Mode

ports can also be configured to support the SYSLOG, SNMP Trap and Buffer Threshold

Alarm functions.

• BufferModeisnotavailabletoPort1(theSetUpPort)ortheNetworkPort.

9.1.3.1. ReadingDatafromBufferModePorts-TextInterface

To check port buffers for stored data, access command mode via the text interface,

using an account that permits Administrator, SuperUser or User level commands, and

type /S [Enter] to display the Port Status Screen. The "Buffer Count" column in the

Port Status Screen indicates how much data is currently being stored for each port.

To retrieve data from buffer memory, go to a free Any-to-Any or Modem Mode Port, then

issue the /R command using the following format: /R xx [Enter]. Where xx is the

number of the port buffer to be read.

Notes:

• The/RcommandisnotavailabletoViewOnlylevelaccounts.

• BuffereddatacanonlyberetrievedviatheTextInterface.Thisfunctionisnot
