p5 Reserved. This parameter is marked by inserting a semicolon
(;) in the command sequence.
p6 A literal string indicating the GENSNC select parameter of an
existing character map (such as 437 or 850) to be used as a
base in which substitutions from this command sequence
may be made. This string may be up to 10 characters in
length and must be specified only if the downloaded character
map uses an existing map as a base. The string is terminated
by a semi-colon (;). The base character map always defaults to
Code Page 437 if an ACT character map is specified and the
downloaded character map is a GR table. If the downloaded
map is a GL table, p6 must specify an existing GL table as the
base or a one-to-one default base is used.
p7 A literal string used to identify the character map in the
Progam Mode Font – Country menu. This string may be up to
20 characters in length and is terminated by a semi-colon (;).
Note that only the first 11 characters of this string are used
for display purposes.
p8-pn A trio of parameters used to specify the actual character map
substitution. A semicolon must separate each parameter
within the trio, and a semicolon must terminate each trio. The
semicolon is not required for the last trio that immediately
precedes the String Terminator (ESC \).
The elements of each trio are defined as follows:
1 A decimal number that identifies the destination
character. This is the character value received from the
host. For example, an upper case "A" has a decimal value
of 65. Values of 32 through 126 and 128 through 255 are
valid for this element.
The first element processed in the first substitution trio
defines whether the map is for GL (7-bit) or GR (8-bit)
substitution. If the first element is between 32 and 126
(inclusive), the map is GL, and the first element of each
trio must also be between 32 and 126. Likewise, if the first
element of the first trio is between 128 and 255, the map
is a GR map and all first elements must fall between 128
and 255. The character substitution map is discarded if
this rule is violated.
2 A decimal number that identifies the source character.
This is the location value of the desired character pattern
in the printer font set. For example, an upper case "A" has
a decimal value of 65. Values of 0 through the last
available character for the currently selected font are valid
for this element.
3 Reserved. A semicolon (;) is required to mark this element
position. A zero is permitted.
