PARAMETERS

The graphics kit can be programmed by means of various integrated commands. Each command

begins with ESC followed by one or two command letters and then parameters. All the commands and

their parameters, such as coordinates and other transfer values, are always expected as bytes. No

separating characters, such spaces or commas, must be used between them. The commands require

no final byte such as a carriage return (except for the string $00).

A..Z, L/R/O/U .................................... All commands are transferred as ASCII characters.

Example: G= 71 (dec.) = $47 initiates the straight-line

command.

x1, x2, y1, y2 .................................... Coordinates are transferred with 1 byte.

Example: x1= 10 (dec.) = $0A

ESC .................................................. 1 byte: 27(dec.) = $1B

n1,n2,no,sv,ev,value,pat,ret,

frm,data ........................................... Numerical values are transferred with 1 byte.

Example: n1=15(dec.) = $0F

For Turbo Pascal write(aux, chr(27), 'Z', 'L', chr(7), chr(3), 'Test', chr(0));

For C

fprintf(stdaux, "\x1BZL%c%c%s\x00", 7, 3, "Test");

For Q Basic

OPEN "COM1:9600,N,8,1,BIN" FOR RANDOM AS #1

PRINT #1,CHR$(27)+"ZL"+CHR$(7)+CHR$(3)+"Test"+CHR$(0)

PATTERN

A pattern type (mst = 0..7) can be set as a parameter with some commands. In this way, rectangular

areas, bar graphs and even texts can be linked to different patterns and displayed.

The following fill patterns are available:

pat=0

pat=1

pat=2

pat=3

pat=4

pat=5

pat=6

pat=7
