Back in the day, those characters were used to literally move carriage on a teletype machine. Most default terminal serial connections thus don’t transmit them since they are emulating this now lost functionality.<div class=""><br class=""></div><div class="">So setting the terminal connection to raw makes sense to me as it’s saying “pass ALL characters, even the old school terminal control characters”.</div><div class=""><br class=""></div><div class="">It took me about a week one time to figure out this was happening while working with a set of serial barcode scanners as it would drop bytes only *some times*. It turned out to be only when the bytes ended up including control character numbers, which were being stripped out. I ended up almost re-writing everything before finally figuring it out. Oh well.<br class=""><div class=""><br class=""><div class="">
