    (system flash) and the video memory chip under the DRAM memory. Like a PC, this area contains the BIOS and video buffers. The upper memory area also contains PC card memory and Intermec JANUS driver software. The 384K upper memory area maps just above 640K conventional memory.

  • Page 363: Ram Drive

    The RAM drive uses 256K of extended memory. If you are not using a PC card, Intermec recommends that you use the RAM drive for data files that you save or update frequently. The RAM drive is not as secure as a PC card since the drive is erased when you cold boot the JANUS device (unless you press during memory test).

  • Page 364: High Memory Area (Hma

    39 nugget Specifications High Memory Area (HMA) The high memory area (HMA) is a 64K block of memory, starting 16 bytes below the 1024K mark, and is the first 64K of extended memory. Since HMA can only hold one item, the first program that requests HMA uses it, regardless of the size of the program.

  • Page 368: Interlnk

    The device running Interlnk is the client and is used to enter commands. The device responding to commands is the server. For help installing and running Interlnk, see “Different Ways to Communicate With the JANUS 2050” in Chapter 6. The command to begin running Interlnk is:...

  • Page 369: Interlnk.exe

    JANUS 2050 Vehicle-Mount Computer User’s Manual (4MB) INTERLNK.EXE This device driver redirects requests for operations on Interlnk drives or printer ports to Intersvr drives or printer ports. You must load this device driver in the CONFIG.SYS file of the device running Interlnk (the client).
  • Page 370 /noprinter switch, the Interlnk program does not load code that redirects printers. If you specify the /com switch, the program does not load code that supports parallel ports. Intermec recommends using the /noprinter and /com switches when INTERLNK.EXE is loaded on the device.
  • Page 371 JANUS 2050 Vehicle-Mount Computer User’s Manual (4MB) INTERLNK.EXE (continued) Notes: (cont.) Limitations These commands do not work on devices running Interlnk: CHKDSK DISKCOMP DISKCOPY Interlnk does not redirect network, CD-ROM drives, or any other device that uses a redirection interface. For example, you cannot access a network drive that was redirected before Interlnk was started.

  • Page 372: Intersvr

    When you run Intersvr in conjunction with Interlnk, it provides serial file transfer capability through redirected drives, and printing through redirected printer ports. For help installing and running Intersvr, see “Different Ways to Communicate With the JANUS 2050” in Chapter 6. Type this command to begin running Intersvr: Syntax:...
  • Page 373 JANUS 2050 Vehicle-Mount Computer User’s Manual (4MB) Intersvr (continued) Notes: (cont.) Copying the files from the reader If you do not have the MS-DOS Programs companion disk, which contains the Interlnk and Intersvr files, you can copy the files from the reader. You need to connect the host computer to the reader using a 7-wire, null-modem serial cable and the Mode command must be available on the host computer where you are installing Interlnk.

  • Page 374: Power.exe

    POWER.EXE POWER.EXE lets you adjust the JANUS 2050 power management at the DOS prompt. It provides power-saving features and an application program interface (API) that applications can use. POWER.EXE works through the Advanced Power Management (APM) interface. IRL programs and programs that use Reader Services do not require POWER.EXE.

  • Page 375: Auto-Loader Batch Files

    When you install Auto-Loader onto your host computer, eight batch files are copied to your host computer. You will use these batch files to change the contents of drive C on the JANUS 2050: • LOAD_USA.BAT or LOADLANG.BAT • LOADADD.BAT •...

  • Page 376: Using Load_Usa

    39 nugget Using LOAD_USA LOAD_USA creates an image file that contains only the three startup files in the C_FILES\COMMON directory: AUTOEXEC.BAT, AUTOINST.BAT, and CONFIG.SYS. Then LOAD_USA loads the image file onto drive C, deleting all the files currently on drive C. Here is the syntax for LOAD_USA: load_usa Note: If you installed Auto-Loader for a DOS NLS country, the LOAD_USA batch...
  • Page 377 JANUS 2050 Vehicle-Mount Computer User’s Manual (4MB) The next tables describe how the two LOADADD commands work depending on the information you include in the command and whether you installed Auto-Loader for a DOS NLS country. Command: DOS NLS Support?

  • Page 378: Using Loadimg

    39 nugget Using LOADIMG LOADIMG loads the image file that you specify on the command line on drive C. LOADIMG overwrites all files currently on drive C. You must have created the image file already with the MAKENEW, MAKE_USA, LOADADD, LOADNEW, LOADLANG, or LOAD_USA. You may have renamed the image file from its default name, NEWDRV_C\DRIVEC.IMG.

  • Page 379: Using Loadximg

    JANUS 2050 Vehicle-Mount Computer User’s Manual (4MB) Using LOADXIMG LOADXIMG loads the default image file, NEWDRV_C\DRIVEC.IMG, to drive C. LOADXIMG overwrites all files currently on drive C. You must have created the image file already with the MAKENEW, MAKE_USA, LOADADD, LOADNEW, LOADLANG, or LOAD_USA commands.

  • Page 380: Using Makenew

    39 nugget Using MAKENEW MAKENEW creates an image file that contains any files you include in the command line. If you do not specify startup files in the command line, MAKENEW adds the three default startup files in C_FILES\COMMON to the image file.
