Error: CGIPATH and CON-CGI DISPLAY drivers, how to set
Solution or Workaround
PRODUCT: PC ARC/INFO
When starting ARCPLOT or ARCEDIT, or the Understanding GIS (UGIS) tutorial SML's (&RUN INTRO or &RUN PROJDB), one of two error messages may occur:
"GRAPHICS DEVICE MUST BE A MONITOR. GRAPHICS DEVICE MUST BE A MONITOR. GRAPHICS DEVICE MUST BE A MONITOR." (continuous scrolling)
"serial comms driver V5 com2 (IRQ level.) gss-cgi lahey fortran90 /fileapp extender binding version 1 copyright ematak ... error -3003 run con-cgi program serial comms driver V5 com2 (IRQ level.) *** com2 driver removed ***"
The CGIPATH has not been as an environment variable and/or the [ARC] level program CON-CGI has not been run to set up a DOS DISPLAY driver.
Warning: WARNING: The instructions below include making changes to essential parts of your operating system. It is recommended that you backup your operating system and files, including the registry, before proceeding. Consult with a qualified computer systems professional, if necessary.
ESRI cannot guarantee results from incorrect modifications while following these instructions. Therefore, use caution and proceed at your own risk.
Caution Step #1 gives different instructions for specific Operating Systems; be sure you use only those that pertain to your OS, and proceed to Step #2.
1-A. For Native MS-DOS, Windows 95 and Windows 98: The following line needs to be added in your C:\AUTOEXEC.BAT file:
Insert the above line just below the line in the C:\AUTOEXEC.BAT file which reads:
SET ARC=C:\ARCEXE ---------------------
1-B. For Windows NT 3.5.1:
See document #67.2125 PCAI35: Windows NT 3.5.1 - Installation instructions. -------------------
1-C. For Windows NT 4.0:
See document #7.2358 PCAI35: Windows NT 4.0 - Installation instructions
2. Save the file and re-boot the PC. It will be necessary to run the [ARC] CON-CGI program and choose a DOS video DISPLAY driver before you use ARCPLOT, ARCEDIT, or the UGIS tutorials again. If you do not see your exact DOS video driver availble here are 5 recommended choices that work on most PC's:
IBMVGA12.SYS HRVGA.SYS (Standard 640 x 480 VGA) HRVGA.SYS (Everex Viewpoint) HRVGA.SYS (VESA Standard) <-- for video cards with a VESA compliant BIOS CGIVESA8.SYS <-- for video cards with a VESA compliant BIOS
In order to use ARCEDIT, ARCPLOT, or the UGIS tutorial it is required that you be in either native MS-DOS or in a FULL SCREEN DOS COMPATIBILITY BOX from within Windows. To enter a FULL SCREEN MS-DOS COMPATIBILITY BOX use the following combination of keys on your keyboard:
ALT + ENTER
This will toggle the small DOS window (with the Windows interface in the background) into a FULL SCREEN DOS SESSION (you will not see the Windows interface in the background). Perform the "ALT + ENTER" from the [ARC] prompt before you attempt to start ARCEDIT or ARCPLOT. When you are done with your ARCEDIT or ARCPLOT session use the "ALT + ENTER" keys again to toggle back to the smaller DOS windows (now you can see the Windows interface in the backgorund). Only use the Windows Extensions version of ARCEDITW and ARCPLOTW when you can see the Windows interface in the background.
