+# 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+   - DOS machines were getting wrong/outdated DSCDATA files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
+```bash
+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
+```bash
+ls -la "/Volumes/C$/Shares/test/Ate/ProdSW/DSCDATA/"
+```
+Output:
+```
+-rwx------ 1 azcomputerguru staff 65508 Jan 16 12:35 DSCMAIN4.DAT
+```
+
+### Sync DSCDATA to NAS
+```bash
+scp "/Volumes/C$/Shares/test/Ate/ProdSW/DSCDATA/"* root@192.168.0.9:/data/test/Ate/ProdSW/DSCDATA/
+```
+
+### Verify after sync
+```bash
+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

+
+## Configuration Changes
+
+### Files Modified
+
+**NWTOC.BAT (v3.5)**
+- Path: `/Users/azcomputerguru/ClaudeTools/projects/dataforth-dos/batch-files/NWTOC.BAT`
+- Deployed to: NAS `/data/test/COMMON/ProdSW/NWTOC.BAT`
+- Deployed to: AD2 `C:\Shares\test\COMMON\ProdSW\NWTOC.BAT`
+- Changes:
+  - Switched from XCOPY to COPY
+  - Removed all >NUL redirects
+  - Added IF NOT EXIST checks before MD
+  - Added 8 ATE data folder copies (DSCDATA, 5BDATA, 7BDATA, etc.)
+  - Removed machine-specific section
+  - Removed MACHINE variable requirement
+
+**DEPLOY.BAT (v2.4)**
+- Path: `/Users/azcomputerguru/ClaudeTools/projects/dataforth-dos/batch-files/DEPLOY.BAT`
+- Deployed to: NAS and AD2
+- Changes:
+  - Switched all XCOPY to COPY
+  - Simplified output messages
+
+**Sync-FromNAS.ps1 (on AD2)**
+- Path: `C:\Shares\test\scripts\Sync-FromNAS.ps1`
+- Changes: Added new section to sync Ate/ProdSW folder:
+```powershell
+# 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
+- [x] DSCDATA files synced to NAS (completed)
+- [x] 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
