  I run 7 serial ports (9 if you want to count the two USB-to-serial
  converters) on my Win XP PC without any conflict.  Of course,
  the key is to choose the right multiport cards.  I use the single
  on-board port and three Quatech DSC-100 cards (I don't have any
  financial interest in Quatech, I just like their products which
  are not cheap).

  I also run 6 USB devices (4 on-board ports and a 7-port hub in
  one of them).

  (Lists of devices available for the curious.)
