This command queries whether user data is
ready to be picked up an how full the display's
receive buffer is.
This is how the maximum package size that
can be sent by the display can be limited. The
default setting is a package size with up to 128
bytes of user data.
The timeout can be set in increments of 1/100
seconds. The timeout is activated when individual
bytes get lost. The entire package then has to
be sent again.
This command is used to query protocol
settings.
If the most recently requested package contains
an incorrect checksum, the entire package can
be requested again. The reply can then be the
contents of the send buffer (<DC1>) or the
buffer/protocol information (<DC2>).
This command can be used to select or
deselect the eDIP with the address adr.
