The Epson Character Sets are constructed as 8-bit character sets, i.e.
a character is assigned to each bit combination of a byte, with con-
trol commands being assigned to some values in the range from 0 to
31. The standard ASCII characters are assigned to the range from
decimal 32 to 126. The value 127 (DEL) in the Epson emulation has
the function of deleting the last character in the line buffer. The ran-
ge from decimal 127 to 159 in the standard Epson Character Set is
identical with that from decimal 0 to 31, while with extension of
printable characters activated special characters are to be found in
this range. If the Epson character set is activated and the extension
deactivated, the selected character set is the same as the IBM cha-
racter set I . Are both Epson character set and extension activated
the selected set is similar to IBM character set II.
