Command timeout patch

[Yves R. <y.r...@in...>]

Hello people,

I find the timeout code in lib/command.c function GetCommand
works much better with this patch.

Otherwise, it hangs if a character is already present in the
uart, and doesn't timeout if there is none.

While I am at it, why is GetCommand weak?

Cheers,
Y.
