National Replacement Character Set (NCRS)

While 8-bit connections allow the display of multinational characters and special symbols, 7-bit connections cannot because there are fewer characters to display. To allow multinational characters over a 7-bit connection, use the National Replacement Character (NRC) sets. This applies to the DEC VT320-7 and DEC VT220-7 emulations.

An NRC set replaces specific characters from the ASCII table with needed characters for a specific language. The TinyTERM Emulator supports 14 NRC sets.

  • American
  • Dutch
  • Italian
  • Swedish
    • British
  • Finnish
  • Norwegian
  • Swiss
    • Canadian
  • French
  • Portuguese
    • Danish
  • German
  • Spanish
  • As an example of how the NRC set works, assume British is selected as the character set. The only difference between the American character set and the British character set is the hex value 23. The American character set uses a cross-hatch (#) and the British character set uses a pound sign ().

    Look at the IBM PC Character Set chart. A # is displayed in the hex 23 location. If the British character set is selected, this would be changed to . Therefore, whenever a hex 23 is sent or received, a pound sign is displayed..
