# 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   - DOS machines were getting wrong/outdated DSCDATA files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
```

  - Removed machine-specific section
  - Removed MACHINE variable requirement

**DEPLOY.BAT (v2.4)**

```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
