APS-16

6.3.2. Port Buffers

 

The Status Screen lists the amount of Buffer Memory currently used by each port. The APS-16 uses buffer memory in two different ways, depending on the user-selected port mode.

•                      Any-to-Any, Passive, and Modem Mode Ports: When two ports are communicating at dissimilar baud rates, the buffer memory prevents data overflow at the slower port.

•                      Buffer Mode Ports: Stores data received from connected devices. The user issues a connect command (/C) from an Any-to-Any Mode or Modem Mode port to retrieve stored data.

 

If the Status Screen indicates an accumulation of data, the /E (Erase Buffer) command can be invoked to clear the buffer.
