# 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- DOS machines were getting wrong/outdated DSCDATA files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
