I’ve tried a few methods, but they didn’t work. Could you help me? Thank you. October 4, 2026 at 6:07 pm #18558 manjey73Participant For manual submission, set the command format to String. Use HEX and enter A5A5 or B4B4. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic. Log In Username: Password: Keep me signed in Log In
