Operation
6.3.3. Buffer Mode
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.
• Buffer Mode is not available at Ports 1 or 2 (the SetUp Ports) or the
Internal Modem Port (Port 7.)
6.3.3.1. Reading Data from Buffer Mode Ports
To check port buffers for stored data, access command mode via the Text
Interface, using a password and port that permit Supervisor commands, and
type /S [Enter] to display the Status Screen. The "Buffer Count" column
indicates the amount of data 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 /C command using the following format:
/C n [Enter].
Where n is the number of the port buffer to be read.
Note: In order to read data from a given port, your password must
allow access to that port.
If the buffer contains data, the CMS-6R4 will display a prompt that offers the
following options:
• Next Screen: To send data one screen at a time, press the Space Bar.
Each time the space bar is pressed, the next screen is sent.
• Scroll All: To send all data currently stored in the buffer, type 1 and
press [Enter].
• Skip/Connect: To skip sending the buffered data, yet remain connected
to the port, type 2 and press [Enter].
• Erase/Connect: To erase all data currently stored in the buffer, yet
remain connected to the port, type 3 and press [Enter].
• Exit: To exit from Read Buffer mode, press [Esc].
Note: Only one user can read from a port buffer at a time. If a
second user attempts to read from a port that is already being read, an
error message will be sent.
