Dataforth DOS - Session Log: 2026-01-21

Project: Dataforth DOS Update System Client: Dataforth Duration: ~2 hours Status: DSCDATA sync issue fixed, batch files updated

Session Summary

What Was Accomplished

  1. Diagnosed DSCDATA Sync Issue

    • DOS machines were getting wrong/outdated DSCDATA files
    • AD2 had newer files (Jan 2026, DSCMAIN4.DAT 65,508 bytes)
    • NAS had old files (Dec 2025, DSCMAIN4.DAT 64,395 bytes)
    • Root cause: Ate/ProdSW folder was NOT in AD2->NAS sync script

  2. Fixed DSCDATA Sync

    • Manually copied correct files from AD2 to NAS via SCP
    • Updated Sync-FromNAS.ps1 on AD2 to include Ate/ProdSW folder
    • All 8 ATE subfolders now sync automatically

  3. Updated Batch Files

    • NWTOC.BAT v3.5: Uses COPY instead of XCOPY, no >NUL redirects
    • DEPLOY.BAT v2.4: Uses COPY instead of XCOPY

  4. Git Checkpoint Created

    • Commit: fd24a0c - "fix(dataforth-dos): DOS 6.22 batch file improvements and sync fix"

Key Decisions Made

  1. Use COPY instead of XCOPY for all operations

    • Rationale: XCOPY has unpredictable behavior in DOS 6.22
    • XCOPY can hang waiting for input even with /Y flag
    • COPY is simpler and more reliable

  2. Add IF NOT EXIST checks before MD commands

    • Rationale: Avoids "Directory already exists" error messages
    • Cleaner output for users

  3. Update sync script to include Ate/ProdSW

    • Rationale: This folder contains shared ATE data for all machines
    • Was overlooked in original sync script design

Problems Encountered and Solutions

Problem 1: DOS machines getting wrong DSCDATA files

  • Symptom: DSCMAIN4.DAT was 64,395 bytes instead of 65,508 bytes
  • Investigation: Compared AD2 vs NAS file sizes and dates
  • Root cause: Ate/ProdSW folder not in sync script
  • Solution: Added Ate/ProdSW to Sync-FromNAS.ps1, manually synced files

Problem 2: AD2 network connectivity intermittent

  • Symptom: SSH and SMB connections timing out
  • Solution: Used multiple connection methods, eventually mounted via Finder

Commands & Outputs

Check DSCDATA on NAS

ssh root@192.168.0.9 "ls -la /data/test/Ate/ProdSW/DSCDATA/"

Output (before fix):

-rw-r--r--+ 1 root root 64395 Dec 14 20:03 DSCMAIN4.DAT

Check DSCDATA on AD2

ls -la "/Volumes/C$/Shares/test/Ate/ProdSW/DSCDATA/"

Output:

-rwx------ 1 azcomputerguru staff 65508 Jan 16 12:35 DSCMAIN4.DAT

Sync DSCDATA to NAS

scp "/Volumes/C$/Shares/test/Ate/ProdSW/DSCDATA/"* root@192.168.0.9:/data/test/Ate/ProdSW/DSCDATA/

Verify after sync

ssh root@192.168.0.9 "ls -la /data/test/Ate/ProdSW/DSCDATA/"

Output (after fix):

-rw-r--r--+ 1 root root 65508 Jan 21 13:42 DSCMAIN4.DAT

# Sync Ate/ProdSW (shared ATE data folders - 5BDATA, 7BDATA, 8BDATA, DSCDATA, etc.)
Write-Log "Syncing Ate/ProdSW data folders..."
$ateProdSwPath = "$AD2_TEST_PATH\Ate\ProdSW"
if (Test-Path $ateProdSwPath) {
    $ateFiles = Get-ChildItem -Path $ateProdSwPath -File -Recurse -ErrorAction SilentlyContinue
    foreach ($file in $ateFiles) {
        $relativePath = $file.FullName.Substring($ateProdSwPath.Length + 1).Replace('\', '/')
        $remotePath = "$NAS_DATA_PATH/Ate/ProdSW/$relativePath"
        # ... copy logic ...
    }
}

DOS 6.22 Compatibility Notes (Updated)

Commands That DON'T Work

  • XCOPY /I flag - "Invalid switch"
  • XCOPY /D without date - "Invalid number of parameters"
  • 2>NUL (stderr redirect) - "Too many parameters"

  • NUL sometimes causes hanging

Commands That Work Reliably

  • COPY (simple file copy)
  • MD directory (create directory)
  • IF NOT EXIST path*.* (check if directory has files)
  • IF EXIST file*.* (check if files exist)

Best Practices

  • Use COPY instead of XCOPY for flat files
  • Use IF NOT EXIST checks before MD to avoid errors
  • Don't redirect to NUL unless necessary
  • Don't use 2>NUL (DOS 6.22 doesn't support it)

Pending/Incomplete Tasks

Immediate

  • DSCDATA files synced to NAS (completed)
  • Sync script updated to include Ate/ProdSW (completed)
  • Test on a DOS machine to verify files copy correctly

Future

  • Investigate test data database on AD2 port 3000 (user mentioned, couldn't access)
  • Document the testdatadb application if found
