I've updated the Console Mode editions of BBC BASIC to version 0.41. This adds support for serial I/O, for example the EXT# function returns the number of characters, waiting in the serial input buffer, available to be read. I've also added 'animal.bbc' to the set of supplied example programs. https://www.bbcbasic.co.uk/console/#bbcbasic
