4.2.8. ASCII and Text Data Character Types
There are two types of data configuration characters. Both have an important and
have a specific function; both are used within the same data string. Both types are
defined below.
ASCII ( A merican S tandard C ode for I nternet I nterchange) Characters
─ Text Formatted Characters are always written with a “ 0x_ _ _ ” prefix,
which tells the Kernel Program Read-me Trigger to post it as text character
(i.e. 0x120).
─ A code for information exchange between computers using a string of seven
(7) binary digits represents each character.
─ Each character identifies either a alphanumeric symbol (i.e. 065 = A, 066 = B,
etc.) or invokes an on-screen action (i.e. 013 = CR = Carriage Return).
─ One Text Block must be added to the Data String for each character before
formatting it.
─ The data entries use decimal-based ASCII character codes.
─ Complete ASCII Chart found in Appendix IV .
Text Formatted Characters
─ A Text block must be added to the Data String before formatting the next
character.
─ These Text Formatted Characters are used to add a specific message to the
Service Technician, and it is done in combination with the text and with other
ASCII Text Characters.
