Don't feel bad I have a Toshiba Sat. 2805 laptop and it also does not have a serial. But even worse, it does have access to Comm1 or Comm2 so ProntoEdit can't work on it because it only looks at comm1 or 2.
Toshiba claims "We can not offer support on this issue" when asked how to open these comm ports.
So I have to use my POS compaq for programming on-site.
