Critical fix for DOS 6.22 compatibility - NUL is a reserved device name in both DOS and Windows and cannot be used as a file/directory name. Problem: - "T: 2>NUL" attempts to create a file called "NUL" (not allowed) - "IF NOT EXIST T:\NUL" tests for NUL device (unreliable) - "IF NOT EXIST path\NUL" treats NUL as filename (invalid) Solution - Replaced with proper DOS 6.22 tests: - "T: 2>NUL" → "DIR T:\ >nul" (test drive access via directory listing) - "IF NOT EXIST T:\NUL" → "IF NOT EXIST T:\*.*" (test for any files) - "IF NOT EXIST path\NUL" → "IF NOT EXIST path\*.*" (test directory) Note: Using lowercase "nul" for output redirection is acceptable as it redirects to the NUL device, but NUL as a filename/path is invalid. Files updated: - DEPLOY.BAT: Fixed drive and directory tests - UPDATE.BAT: Fixed drive and directory tests - NWTOC.BAT: Fixed drive and directory tests - CTONW.BAT: Fixed drive and directory tests - CHECKUPD.BAT: Fixed drive and directory tests - DOSTEST.BAT: Fixed drive and directory tests Created fix-nul-references.ps1: - Automated script to find and fix NUL references - Preserves CRLF line endings - Updates all BAT files consistently Created monitoring scripts: - monitor-sync-status.ps1: Periodic sync monitoring - quick-sync-check.ps1: Quick AD2-to-NAS sync status check Verification: - All BAT files maintain CRLF line terminators - File sizes increased slightly (4-8 bytes) due to pattern changes - DOS 6.22 compatible wildcard tests (*.*) used throughout Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
