Control Sequence to turn off all character attributes, and then turn on underscore and blink
attributes simultaneously. Alternative sequences which will accomplish the same thing:

Same, but devided in three independent sequences:
ESC [ m (1Bh 5Bh 6Dh)
ESC [ 4 m (1Bh 5Bh 34h 5Dh)
ESC [ 5 m (1Bh 5Bh 35h 6Dh)
Buffered Messages
When the application interest is refreshing a full screen, or a line:
Two control characters, STX and ETX, allow to store the partially received text in an internal
buffer until complete reception is received. Only then it will it be written in the LCD.
ASCII Control Character Codes Implemented
• STX (02h): start of text. Init entering text in the input buffer.
• ETX (03h): end of text. Finish entering data in the input buffer and writs the buffer contents
in the LCD.
If these ASCII Character Codes are not used, data will be immediately represented as soon as it
is received by the display. STX and ETX ASCII control characters cannot be used as parameters
of a VT100 control sequence. Buffered messages can include control sequences with arrays of
characters.
Example: VT100 Data Feedback
