Hello, I'm Carl Tristan Orense. I wanted to let you know that one or more of your recent contributions to RS-232 have been undone because they did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the help desk. Thanks. Carl Tristan Orense 05:09, 27 November 2019 (UTC)
