5.3.2. Port Modes


The APS-16 offers four port operation modes; the Any-to-Any Mode, the Passive Mode, the Buffer Mode, and the Modem Mode. The Port Modes function as follows:

•                      Any-to-Any Mode: Allows communication between connected ports. Any-to-Any Ports can be connected to other Any-to-Any Ports by accessing the Command Mode and issuing ASCII commands. The Any-to-Any Mode is available to all ports.

•                      Passive Mode: Allows communication between connected ports, but does not allow access to the Command Mode. Passive Mode Ports can be connected by accessing the Command Mode from a free Any-to-Any or Modem Mode port and invoking the /C command as described in Section 6.1.1. The Passive Mode is not available to Ports 1 or 2.

•                      Buffer Mode: Allows collection and storage of data received from connected devices. Collected data can be retrieved by accessing the Command Mode from a free Any­to-Any or Modem Mode Port, and issuing the Connect (/C) Command. The Buffer Mode is not available to Ports 1 or 2.

•                      Modem Mode: Allows communication between connected ports and simplifies connection to an external modem. A port configured for the Modem Mode can perform all of the functions normally available in the Any-to-Any Mode. The Modem Mode also allows definition of a Hang-Up String, Reset String, and Initialization String. Any Port can be configured for the Modem Mode.


Port Modes are discussed in detail in Section 6.
