Doing a bit more investigation this evening and it appears that the console
driver for the Beaglebone BSP isn't really implemented properly. Comparing
it with the raspraspberrypi and other bsps the console/console-config.c
file looks very different and doesn't implement the POSIX Termios support
per the latest documentation
https://docs.rtems.org/docs/main/bsp-howto/console.html

When I change my test application to use #define
CONFIGURE_APPLICATION_NEEDS_SIMPLE_CONSOLE_DRIVER instead of #define
CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER it does accept input (albeit
very unreliably).

It looks like if I want console input support for the Beaglebone BSP I am
going to have to implement a better console driver :-/

Cheers,
James
