From 925a76978680c4f1784931444e6ead59df302a0d Mon Sep 17 00:00:00 2001 From: Mike Swanson Date: Mon, 19 Jan 2026 16:41:31 -0700 Subject: [PATCH] fix: Replace NUL device references with DOS 6.22 compatible tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
