Changing a file attribute on Symbol 6846

I need to edit a read-only batch file on the flash rom on the 6846. I can edit other files, but not this batch file. I can edit it in the RamDrive, but lose my changes any time we have to do a cold-boot. Of course there is no 'attrib' command, but is there some other way to accomplish this?

You will need to extract the files from the terminal to be able to edit them normally and then rebuild the hex file to reload on to it.

There are two commands that you may want to try on the terminal but i doubt you will be able to modify the file.

flshctl /w will enable you to write on the flash.
flshctl /ro will disable the write option.

Remove read only files

After copying a batch of files to your Windows PC from a CD or DVD, you may discover that all the copied files carry the read-only flag. The most obvious way to remove the read-only flag from a file is to right-click on its icon, choose "Properties", and uncheck the "Read-only" box. But what if you have hundreds, or even thousands of files marked read-only?
You can batch-remove the read-only flag from multiple files using the attrib command from a command prompt. The Windows Command Line site has a tutorial on commands everyone can use, which includes an explanation of performing this task with the attrib command. The section on the attrib command is titled "Changing file attributes with 'attrib'", and is located about three quarters of the way down the page.
In short, you can remove the read-only flag from a group of files by navigating to their folder from a command prompt and typing attrib -r ./*.* /s. I did this to a folder full of image files with attrib -r ./*.jpg /s.
Bring up a command prompt in Windows XP by clicking Start → Run, typing "cmd", and pressing "OK". In Windows Vista, click Start, type "cmd", and press the Enter key.

Have files on a CD that are read only. How can I remove read only so I can make changes to the files. Thank you.

You can use the xcopy command to remove the read-only attribute while you are copying files from a CD-ROM. Xcopy.exe resets the read-only attributes unless you specify otherwise by using the /k switch (this switch copies attributes). To use this method:

  1. Click Start, and then click Run.
  2. In the Open box, type cmd, and then click OK.
  3. Type xcopy drive letter:\*.* destination /e /h, where drive letter is the CD-ROM drive letter and destination is the path to the destination for the files, and then press ENTER. For more information about command-line switches for Xcopy.exe, type xcopy /? at a command prompt.

How to create simple batch files

Creating a batch file
MS-DOS users
Microsoft Windows and other users

MS-DOS users
To create a basic batch file in MS-DOS, follow the below steps that give you an example of how to create a basic batch file.

  1. Open an MS-DOS command window or get to MS-DOS. Additional information about doing this can be found on document CHDOS.
  2. At the MS-DOS prompt, type: edit test.bat and press enter.
  3. If typed properly, you should now be in a blue screen. Within the screen, type:

    dir c:\windows
    dir c:\windows\system

  4. Once the above three lines have been typed in, click File and choose exit; when prompted to save, click "Yes." Users who do not have a mouse cursor can accomplish this same task by pressing ALT+F to access the file menu, then pressing "X" to exit, and pressing enter to save changes.
  5. Once you are back at the MS-DOS prompt, type: test and press enter. This will execute the test.bat file and begin running the file. Because the first line is pause, you will first be prompted to press a key. Once you press a key the batch file will run line-by-line; in this case, listing the files in the windows and windows\system directories.
If you wish to add more lines to this batch file you would simply type "edit test.bat" to edit the file again.
Additional information about the MS-DOS edit command can be found on our edit command page. Some versions of MS-DOS and bootable diskettes may not have the edit command; if this is the case, you would either need to obtain the file to access this file or use the copy con command.

Microsoft Windows and other users
A Windows user can still use the above MS-DOS steps if they wish to create a batch file. If, however, you're more comfortable using Microsoft Windows or your operating system, you can use any text editor, such as Notepad or Wordpad, to create your batch files, as long as the file extension ends with .bat. In the below example we use the Windows notepad to create a batch file.
  1. Click Start
  2. Click Run
  3. Type: notepad and press enter.
  4. Once notepad is open, type the below lines in the file or copy and paste the below lines into notepad.

    @echo off
    echo Hello this is a test batch file
    dir c:\windows

  5. Click File and click Save; browse to where you want to save the file. For the file name, type "test.bat", and if your version of Windows has a "Save as type" option, choose "All files", otherwise it will save as a text file. Once all of this has been done click the Save button and exit notepad.
  6. Now, to run the batch file, simply double-click or run the file like any other program. Once the batch file has completed running it will close the window automatically.

Symbol PDT 6846 - Scanner won't read 13 digit barcodes (program returns "not on file"). How do we update the scanner application?

This sounds like a programming issue. What application are you using? If you are using a terminal emulation software then you will need to check your host for the issue. If you are using a batch program where the files are stored on the scanner then you will need to check your "validation" files to make sure the code you are scanning is in the scanner.

MS-Dos running a file..

Right click on the file and select edit. This should load it in a text editor.
Now, simply read what it does.

You don't say what the batch file is for, so it's hard to say what you should look for in the file.
