Hi, I would like to purchase the Plugable USB to RS-232 DB9 Serial Adapter (Prolific PL2303HX Chipset) but was wondering if it will support 921.6kbps in a Windows XP computer?
Thanks for posting and for your question!
The short answer is, it should work, since the Plugable USB to RS-232 Adapter supports speeds from 75bps to 12Mbps. A lot also depends however on the device you are actually going to connect to the adapter, so you really need to try it with your own device and see.
Hope this helps!
