) In the automatic entry mode the character symbols in the range from character code low to character code high can be selected without any serial
line communication going on. This is done using the rotary wheel (PCD7.D230) or cursor up / down keys (PCD7.D231 / PCD7.D232). No values
are returned during selection. Pushing the enter key the character code of the chosen character is sent over the serial line as response. Typical
use is the setting of start value ‘0’, end value ‘9’ which yields an automatic decimal selection. Keymode 0x30 (‘0’) and 0x31 (‘1’) allow the selection
of the up/down direction. This mini data entry function is also used in the setup menu and can be verified there for it’s working.
2
) The terminals have a storage option for 16 full sized background memory screens (each 120 x 64 Pixel). The command makes a ‘snapshot’ into
memory of the currently shown screen. The stored screen can be replayed in transparent or non transparent mode. In transparent mode its content
is only rewritten over empty character fields. This can be used for menu masks.
The download / upload screen line commands are used to upload / download one line (120 x 8 Pixel) of one of the 16 background screens. The
command can also directly download into the symbol storage for symbol display. This goes in background without touching the displayed screen.
3
) The pixel map that is displayed at a specific character code is free to define. The pixel map can be downloaded for each individual upper page
character code (code 128 .. 255) with for each character code storage from 1 character field (6 x 8 pixel) to 9 character fields (18 x 24 pixel) using
the load next command. This can be used to load free to define symbols for alternative alphabets, and display of larger characters that can be
shown easily sending merely the joint 1 byte character code.
4
) Read / Set Parameter allow the change of serial mode and timing parameters. Baudrate changes get active at a warm restart.
5
) The actual access position is shown by a cursor that inverts the actual displayed pixel. This cursor can be set to blinking, permanent or off. The
cursor type can be underline (2 pixels vertical, 1 character field wide) or full (all 8 pixels). The default is underline, blinking.
6
) In the auto cursor mode the cursor moves without serial communications going on using the rotary wheel or cursor up / down / left /right keys.
The cursor display mode is such as set before.
A box (x-delta, y-delta) is defined in which the cursor moves. The box can be a vertical bar or horizontal bar or a combination. Pushing the entry
the actual position is returned. This built-in mini browser function can be used for a selection of a menu entry.Keymode 0x30 (‘0’) and 0x31 (‘1’) al-
low the selection of the up/down direction.
