Don't repeat the register access part of the code 4 times times or triple-space statements. This fixes half of the style bugs in rev.1.172. Hardware flow control of 16650As is still officially unsupported. I was mistaken about it being broken. It is broken in 16650s but is fixed in 16650As except for the maximum trigger level (which is no longer used). Testing of the 16650's broken hardware flow control watermarks by programming them on 16950s showed that their effects are not too bad if the fifo size and trigger level are reasonably large (16 is much better than 8). |
