The console interface provides support for executing commands over stdout (typically a serial port).
The connection can run in 2 modes:
- normal, standard GOSH interface (Human Machine Interface), echo characters, prompt, etc.
- cci, Computer Computer Interface. Simple text interface, but with tagged output format - easier to parse by a computer.

@deftypefnx Supplemental {unsigned long int} strtoul (const char *@var{string}, @
char **@var{endptr}, int @var{base})
The @code{strtol} function converts the string in @var{string} to a
long integer value according to the given @var{base}, which must be
between 2 and 36 inclusive, or be the special value 0. If @var{base}
is 0, @code{strtol} will look for the prefixes @code{0} and @code{0x}
to indicate bases 8 and 16, respectively, else default to base 10.
When the base is 16 (either explicitly or implicitly), a prefix of
@code{0x} is allowed. The handling of @var{endptr} is as that of
@code{strtod} above. The @code{strtoul} function is the same, except
that the converted value is unsigned.
