                          7. UTILITY MODULES
                                   
   Novaterm provides a set of external programs to supplement the
   functionality of the software. This section describes the
   operation of each of these programs (with the exception of the
   Text Editor and BBS Mode, which are covered in Appendices A and
   B).
   
  7.1 ASCII table editor
  
   The ASCII table editor allows you to modify the mappings used to
   convert incoming data into readable text. Because the Commodore
   64 assigns different ASCII values to characters than the rest of
   the world, these tables are necessary to convert incoming
   characters into values that are proper for the Commodore.
   
   Each file actually contains two tables: a "transmit" table and a
   "receive" table. The transmit table converts your keystrokes
   into ASCII values that can be transmitted over the modem; the
   receive table converts incoming characters into ASCII values
   that can be displayed on your screen. There are 256 possible
   characters, and each one has a mapping in both the transmit and
   receive tables.
   
   When you run the ASCII table editor, you are asked for the name
   of a translation table. After you specify the name of a table,
   the first 64 values in the transmit table is displayed, along
   with a list of commands at the top of the screen. The table is
   laid out such that the first number in each entry is the value
   before conversion, and the second number is the converted value.
   
   The cursor keys move the highlight bar around the visible
   portion of the table. The following commands are also available:
   
   Key: Modify the converted value of the current selection by
   pressing a keyboard character. The ASCII value of the key you
   press appears as the converted value.
   Number: Modify the converted value of the current selection by
   typing in a number.
   Page: Switch to the next 64 values in the current table.
   Table: Toggle between the transmit table and the receive table.
   Load: Load a new ASCII table.
   Save: Save the current ASCII table.
   
  7.2 Font editor
  
   The font editor allows you to modify the appearance of
   characters as they are displayed on the screen. The font editor
   handles both 40-column and 80-column fonts.
   
   When you run the font editor, it initially displays the default
   40-column font, which is copied from the Commodore 64's
   character ROM. You can switch between 40-column and 80-column
   mode by pressing the X key.
   
   Loading a font and editing characters involves the same key
   commands in either mode. To load a font into memory, press the L
   key and supply the name of a font file.
   
   Use the cursor keys to select a character to edit. The character
   number is displayed, and a blown-up version of the character is
   reproduced for editing purposes.
   
   To edit the character, press RETURN. In edit mode, use the
   cursor keys to move the asterisk, and use the SPACE key to turn
   a pixel on or off. As you modify the character, you'll see the
   change take effect in the actual-sized character. Press RETURN
   again when you are finished editing. When you are finished
   editing the font, press S to save it.
   
   The 40-column font editor has a number of extra commands that
   are useful for manipulating characters:
   
   Reverse: Invert every pixel in the current character.
   Flip: Do a vertical flip of the character.
   Mirror: Do a horizontal flip of the character.
   Rotate: Rotate the character 90 degrees clockwise.
   Upspin: Shift the character up one pixel.
   Downspin: Shift the character down one pixel.
   Leftspin: Shift the character left one pixel.
   Rightspin: Shift the character right one pixel.
   Fill buffer: Copy the current character into the buffer space.
   Write buffer: Copy the pattern in the buffer to the current
   character.
   Copy chars to reverse: Copy the first half of the character set
   to the second half, reversing each character at the same time.
   
  7.3 Configuration
  
   The configuration program is automatically started if you try to
   run Novaterm without a configuration file. It can also be used
   at any time to reset the configuration to a new state. See
   section 1.2, Starting up the program for a description of the
   various options set by the configuration program.
