Client language
-This section should talk about the client language.
+
+ There are two language commands that can be called by the client:
+ pictograms_get and pictogram_set.
+
+
+
+
+
+ pictograms_get
+
+
+ This command may be called by a client to get a list of
+ available pictograms. If pictograms are not support by the
+ particular version of LCDd, it will respond with an error
+ message (huh? unknown command).
+
+
+ Clients should either check the version number returned as
+ response to the 'hello' command or the response to
+ 'pictograms_get' to check if LCDd supports pictograms before
+ calling 'pictogram_set' (see below).
+
+
+
+ The response will be a string in the format:
+
+
+ pictograms pictogram list...
+
+
+ The pictogram list will be a sequence of pictogram
+ definitions separated by a space character. Each pictogram
+ definition consists of up to four fields separated by a colon.
+
+
+
+
+ Name
+
+
+ The text representation of the pictogram name.
+
+
+
+
+ Type
+
+
+ The type of the pictogram: 'n' for numerical pictograms
+ and 'b' for boolean type pictograms.
+
+
+
+
+ Group ID
+
+
+ The Group ID is optional and if present is a number greater than zero
+ that models the driver's idea of a several pictograms that form a group. This
+ may e.g. be used for media source pictograms.
+
+ The group ID is only informational for the client and is not used
+ within LCDd. The driver however may make use of groups internally.
