Re: ser_posix.c: is select()ing for the write descriptoruseful at all?

I have tested the patch on the following with no problems. I did  
notice that the new version is 1~2 seconds slower but this could be  
to do with other factors as I'm comparing to version 5.1.

  System Version:       Mac OS X 10.4.9 (8P135)
  Kernel Version:       Darwin 8.9.0
