DESCRIPTION OF THE RD-GL II COMMAND
40,40 [TERM]
These two parameters indicate that the DPX-3300 has 40 plotter units within a
1 mm
x
1 mm area of both X- and Y-axis directions, [TERM] is the output terminator
of RS-232C, For more information, see "ESC.M Command" of
8.4.1
"Handshake
Mode Commands" in CHAPTER 8,
Remember: For the actual use in a program, you must have opened the RS-232C
port first by using the "OPEN" statement of the computer,

OF COMMAND
***
20 OPEN "COM1:9600,N,8,1" AS #1
30 PRINT #l."OF;"
40 INPUT #l,UX,UY
50 PRINT UX,UY
(For only serial connection)
• Function:
The OH command outputs to the computer the coordinate values at the lower left
corner (LU and upper right corner (UR) of the maximum plotting area (hard-clip).
• Format:
OH [Terminator]
• Example:
PRINT #l,"OH;"
• Explanation:
When receiving the OH command, the DPX-3300 outputs the integer coordinate values
of LL and UR in ASCII as follows:
XLL, YLL, XUR, YUR [TERM]
The DPX-3300 outputs a minus sign" - " for negative coordinates and ignores the
first 0 and plus sign
"+ ".
The maximum plotting area varies with setting the DIP
Switch 1
(j)
(see 3.6 "SETTING FUNCTIONS FOR PAPER SIZES" in CHAPTER 3.) The
DPX-3300 outputs in real number the values of Table IW-l shown in the section of
"IW Command". And using
com
nd, you can set a window in the maximum
plotting area to determine a plotting area for that window. The IW cornrnand has
