cdc-emit ( c -- ) Emits one character to the USB-CDC interface. Blocking if the Buffer is full. cdc-key ( -- c ) Waits and gets one character from the USB-CDC interface. Blocking if the buffer is empty. cdc-emit? ( -- ? ) Ready to send a character. Buffer is not full. cdc-key? ( -- ? ) Checks if a character is in the buffer.
serial-emit ( c -- ) Emits one character to the UART interface. Blocking if the Buffer is full. serial-key ( -- c ) Waits and gets one character from the UART interface. Blocking if the buffer is empty. serial-emit? ( -- ? ) Ready to send a character. Buffer is not full. serial-key? ( -- ? ) Checks if a character is in the buffer. baudrate!
