    Your code isn't any better than the original. You've just distributed the delays differently. But both versions fail to transmit a full stop bit, which becomes a problem when sending bytes back-to-back. Commented Feb 9 at 15:51
  • Start bit is the important part, stop bit isn't quite needed here as the receiving routine expects only 8 bits after this start bit, and then just stops reading after the whole byte has been read. I just cannot locate the problem... Commented Feb 9 at 17:06
  • @DaveTweed Compared to the code originally in the question when I wrote my answer, the answer solved the three pinpointed problems. These improvements were later incorporated in the code in the question. Commented Feb 9 at 20:57
  • @Milos There might be some timing problems on the ATtiny13. A possible solution to this is added to my answer. Commented Feb 9 at 20:57
