Re: Dell laptop serial port
It's notable that the highest common serial speed (115200) is faster than USB 1.0. Keep in mind that the USB side has to transmit all data, all signal lines, and configuration over its Rx/Tx lines.
I'm willing to bet money that some manufactures have not designed for USB 2 or higher-baud applications.
Rule of thumb: if it doesn't work with the dashboard, don't use it. The dashboard runs at 115200 and is not configurable. Dig around if you need suggestions.
