Subject: [PATCH] Fix one bit signals value extraction

`line.substring(0,0)` results in a zero-length string. As the documentation for `String::substring` says: "The substring begins at the specified beginIndex and extends to the character at index endIndex - 1.".

So to extract the first character, `startindex` must be `0` `endindex` must be `1`.
