5.3.16. Display System Status
This command displays the upstream line 21 data channels that are turned on (i.e.: upstream data being
passed through to the output) and the number of bytes of memory remaining to store articles and XDS
packets.
Command:
^AA<cr>
Default:
none
Examples:
^AA<cr>
Returns:
Example with all channels On:
Memory Status: Avail-005453 # Segments-000011 Largest Avail-005453
Channel Status:
Field 1:C1 C2 T1 T2 ON
Field 2:C3 C4 T3 T4 XD ON
Example with all channels On except T3:
Memory Status: Avail-005453 # Segments-000011 Largest Avail-005453
Channel Status:
Field 1:C1 C2 T1 T2 ON
Field 2:C3 C4 T4 XD ON
5.4. TEXT ARTICLES
When the Article state is active, text data can be entered and stored as complete messages. These
messages can be transmitted in any order, any number of times, in any of the text channels. Display
attributes contained within the articles (such as color, etc.) specifically coded for one data stream will be
translated into the appropriate codes for the text channel they are ultimately inserted into.
The message can be kept in memory or deleted when you have finished transmitting it. Articles will be lost
from the article memory in the event of a power loss. The MIO–CCE–4K/3G uses an advanced memory
allocation scheme that enables it to store a virtually unlimited number of articles at one time. The only
requirement is the maximum amount of random access memory available.
The command protocol allows editing of each line of the message by use of the ^H (backspace) and ^X
(delete line) characters before the <cr> is input. A delay of 1 to 9 seconds can be inserted into the article
by inserting ^Bn into the article. (n is the number of seconds of delay desired)
Once a text channel is put into Article state, upstream data on that channel will be blocked from the output
queue. A data channel will be in the article state as long as any article is assigned to its output queue.
5.4.1.
Input Article
This command allows the user to input an article to the article memory and assign it to the output queue of
one of the text data channels.
