HELP !! HP Jornada 720 "Newbie Question's.......

Having received as a gift from our Son we need a little info.... Whats the latest version of active sync we should use. The unit also came with a 3Com LAN 10/100 PC Card model 3CXFE575CT XJACK where to find drivers and can this unit be active sync using the LAN card if we find drivers Would we be looking for CE driver's?? or something else. The unit came with a serial to Hp jornada connection and there aren't computers in the house with a serial port .

Thanks in Advance

you should read the support section here (http://www.hpcfactor.com/support/). most of your questions will be answered there, if not, just tell us
oh and about a serial connection.. you can try infrared connection too.. or buy an usb-serial converter.

I'd also add that you should visit sync software and hardware (the HCL) as well as support.
You want ActiveSync 3.8.
