8.2. 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 communicate with other ports, but cannot enter command mode, and therefore cannot invoke commands to redefine port parameters, display status, and etc.

Passive Mode Ports can be connected by accessing command mode from a free Any-to-Any Mode or Modem Mode Port, and invoking the Third Party Connect or Resident Connect Command as described in Section 8.1.1. Passive Mode ports will not buffer data, except during baud rate conversion.

Notes:

A Passive Mode Port is not allowed to access command mode.

In order to ensure supervisor access to important command functions, the Passive Mode is not available to Ports 1 and 2 (SetUp Ports).

The Internal Modem Port cannot be configured as a Passive Mode Port. On the APS-8M, Port 8 is the Internal Modem Port, and on the APS-16M, Port 17 is the Internal Modem Port.

8.3.Buffer Mode

Ports configured as Buffer Mode ports will collect data from the connected device and store it in the APS’s statically allocated memory. Each port features a fixed length, fixed position data buffer.

The Buffer Mode allows collection of data from various devices without the requirement that all devices use the same communication parameters (e.g. baud rate, parity, etc.).

Notes:

Buffer Mode Ports cannot access command mode.

In order to ensure supervisor access to important command functions, the Buffer Mode is not available to Ports 1 and 2 (SetUp Ports).

The Internal Modem Port cannot be configured as a Buffer Mode Port. On the APS-8M, Port 8 is the Internal Modem Port, and on the APS-16M, Port 17 is the Internal Modem Port.
