If the port's buffer is empty, the CMS-32 will send a message
which reads "Connected xx, Buffer Empty"; where "xx" is the
port number. If the buffer contains data, the CMS will display a
prompt that offers four options:
·Next Screen: To scroll through data one screen at a time,
press the [Space] bar. Each time the space bar is pressed,
the next full screen of data will be sent.
·Scroll All: To send all data without pausing, press .
·Skip/Connect: To connect to the buffer port without
sending stored data, press .
·Erase/Connect: To connect to the buffer port and erase
stored data, press . Note that buffered data will be erased
immediately and will not be sent.
Note: All four of these options also allow
pass-through communication with the device
connected to the Buffer Mode port.
To clear data from the buffer, use the Erase/Connect option, or
go to a free Any-to-Any or Modem Mode Port with Supervisor
Level command capability, and issue the /E (Erase Buffer)
command using the following format:
/E xx [Enter]
Where xx is the number or name of the port buffer to be cleared.
7.3.2. Port Buffers
The Status Screen lists the amount of Buffer Memory currently
used by each port. The CMS 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 data.
Buffer Mode ports can also be configured to use the Syslog
Function or SNMP Trap function.
If the Status Screen indicates an accumulation of data, the /E
(Erase Buffer) command can be invoked to clear the buffer.
