fgets() call doesn't use uart

[msmithRT]

Although redirect.c is included and printf() calls use the uart as expected, fgets() calls don't seem to be able to detect incoming characters.

This isn't critical, since I just wrote a quick wrapper for the app_uart_get() function that does exactly the same thing, but clearly I'm missing something in how the redirect works.

redirect.c is not full redirect it only replaces a few functions. gets() may work all the f.. stuff will not.

proper implementation is here

That seems to be true, but why is that? Do the f.. functions not use __getchar and __putchar?

It's also kind of funny that gets() might work, when it's the crazy-unsafe version of the input call.

the f.. functions are for file stream.  It is not guaranty that it is implement with __getchar __putchar.
