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.
