Does the Plugable USB Serial Converter (PL2303-DB9) support 2 stop bits? I’m using the converter to support configuration updates to a AV Receiver via its RS-232 port which requires 2 stop bits.
Thanks for posting with your questions. In a word, yes. Further details are in Prolific’s product details sheet linked below (pg 7), but please let me know if you’ve any other questions.
