The parameter
name identifies the name of the article. The article can subsequently be referred to by
its name. If the article name already exists, the new article with the same name will replace the
previous article.
The
tc parameter identifies the text channel number that the article will be placed into.
The
rc parameter identifies the number of times the article will be repeated. Values of 9999 or FFFF
indicate that the article should be repeated indefinitely. An article’s repeat count will be decremented
each time the article is output in each output data stream.
The
k/d parameter identifies whether the article should be kept or deleted when it has been transmitted
the specified number of times.
The
o/h parameter identifies whether the article should be placed into the output queue or whether it
should just be held in memory for later use.
The
n/l parameter identifies whether the article should be placed as the first article in the output queue
or the last article in the queue.
All subsequent data is part of the article until ^C is received. The encoder will respond to each line of
the article with a ‘>’ prompt while the article is being defined.
Examples: ^A0<sp>Test<sp>T1<sp>5<cr>
This is the first line<cr>
and this is the last line ^C
A two line article called ‘Test” will be placed at the end of the Text 1 output queue. The
article will be deleted after it is output 5 times.
4.4.2. Output Article
This command allows the user to put an existing article (defined by the Input article command) into the
output queue of the specified text data channels. An article may be put into an output queue more than
once.
Command: ^A1<sp>name<sp>tc<sp>rc<sp>k/d<sp>o/h<sp>n/l<cr>
Default:
tc last text channel the article was sent to
rc current repeat count
k/d last keep/delete status specified for the article
o/h O
n/l last next/last status specified for the article
The parameters have the same meaning as for the Input article command. If the
o/h parameter is H
then this command may be used to change other attributes of the article without outputting it.
The parameter
name specifies the name of a previously defined article.
