"Mass mind" knowledge sort ... On laptops / PCs with RS232 asynchronous serial ports, is 300 baud capability still universally available? I'd expect this to be a function of the UART, but there's no telling the madness that can be managed with a computer. Has anyone met a system where this is not the case and only higher baud rates are supported? If so, what was the lowest supported baud rate?
