42 * When there is no UART (e.g. Quickturn), the host should write a complete
43 * input line directly into cbuf and then write the length into vcons_in.
44 * This may also be used when there is a real UART (at risk of conflicting with
45 * the real UART). vcons_out is currently unused.

50 /* Output (logging) buffer
51 * Console output is written to a ring buffer log_buf at index log_idx.
52 * The host may read the output when it sees log_idx advance.
53 * Output will be lost if the output wraps around faster than the host polls.
57 /* Console input line buffer
58 * Characters are read one at a time into cbuf until <CR> is received, then
59 * the buffer is processed as a command line. Also used for virtual UART.
