### Description

channelinformation OBJECT-TYPE
SYNTAX OCTET STRING
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"Auxiliary information to allow a printing application to
use the channel for data submission to the printer. An
application capable of using a specific PrtChannelType
should be able to use the combined information from the
prtChannelInformation and other channel and interface
group objects to 'bootstrap' its use of the channel.
prtChannelInformation is not intended to provide a
general channel description, nor to provide information
that is available once the channel is in use. The
encoding and interpretation of the prtChannelInformation
object is specific to channel type. The description of
each PrtChannelType enum value for which
prtChannelInformation is defined specifies the
appropriate encoding and interpretation, including
interaction with other objects. For channel types that
do not specify a prtChannelInformation value, its value
shall be null (0 length). When a new PrtChannelType
enumeration value is registered, its accompanying
description must specify the encoding and interpretation
of the prtChannelInformation value for the channel type.
prtChannelInformation semantics for an existing
PrtChannelType may be added or amended in the same
manner as described in section 2.4.1 for type 2
enumeration values. The prtChannelInformation specifies
values for a collection of channel attributes,
represented as text according to the following rules:
1. The prtChannelInformation is coded in the NVT ASCII
character set. It is not affected by localization.
2. The prtChannelInformation is a list of entries
representing the attribute values. Each entry consists
of the following items, in order:
a. a keyword, composed of alphabetic characters (A-
Z, a-z), that identifies a channel attribute,
b. an Equals Sign (=) to delimit the keyword,
c. a data value, consisting of NVT ASCII graphics
characters (codes 32-126),
d. a Line Feed character (code 10) to delimit the
data value.
No other characters shall be present. Keywords are
case-sensitive. Conventionally, keywords are
capitalized (including each word of a multi-word
keyword), and, since they occupy space in the
prtChannelInformation, they are kept short.
3. If a channel attribute has multiple values, it is
represented by multiple entries with the same keyword,
each specifying one value. Otherwise, there shall be at
most one entry for each attribute.
4. By default, entries may appear in any order. If
there are ordering constraints for particular entries,
these must be specified in their definitions.
5. The prtChannelInformation value may represent
information that is not normally coded in textual form,
or that is coded in a character set other than NVT
ASCII. In these cases, whatever symbolic representation
is conventionally used for the information should be
used for encoding the prtChannelInformation. (For
instance, a binary port value might be represented as a
decimal number, Unicode would be represented in UTF-8
format.)
6. For each PrtChannelType for which
prtChannelInformation entries are defined, the
descriptive text associated with the PrtChannelType
enumeration value shall specify the following
information for each entry:
Title: Brief description phrase, e.g.: 'Port
name,'Service Name,'
Keyword: The keyword value, eg: 'Port,' 'Service'
Syntax: The encoding of the entry value, if it
cannot be directly represented by NVT ASCII,
Status: 'Mandatory,' 'Optional,' or 'Conditionally
Mandatory,'
Multiplicity: 'Single' or 'Multiple,' to indicate
whether the entry may be present multiple times,
Description: Description of the use of the entry,
other information required to complete the definition
(e.g.: ordering contstraints, interactions between
entries).
Applications that interpret prtChannelInformation should
ignore unrecognized entries, so they are not affected if
new entry types are added.
Additional information:
After telling the peripheral how many logical
channels will be used, the IIO card tells the printer the
value of the information value of each of the channels. The
information is auxiliary information used in conjunction with
the channel Type."
