In comment #2 above I managed to not copy-paste the last line of the function,
so here is the complete function:

public string ReadLine (){
    CheckOpen();
    List<byte> bytes_read = new List<byte>();
    byte[] buff = new byte[1];
    int new_line_offset = 0;

    while(true) {
        //int n = stream.Read(buff, 0, 1);
        int n = FackeRead(buff);

        if(n == -1) {
            break;
        }

        bytes_read.Add(buff[0]);


        if(bytes_read.Count >= new_line.Length) {
            bool isNewLine = true;

            //check if we have read a NewLine string.
            for(int i = 0; i < new_line.Length; i++) {
                if(bytes_read[new_line_offset + i] != new_line[i]) {
                    isNewLine = false;
                    break;
                }
            }

            if(isNewLine) {
                //Remove the NewLine string from the read line.
                bytes_read.RemoveRange(new_line_offset, new_line.Length);
                break;
            }

            new_line_offset++;
        }
    }

    return new String(encoding.GetChars(bytes_read.ToArray()));
}
