Yes back in the old days. I remember using serial port to communicate with another computer. But serial and parallel ports are being replace by faster technology like USB 2.0 and FireWire.
If you do not intend to use a network after you have transfered the files, then just buy a serial cable, and go into the files and settings transfer wizard.
are all the serial cables the same. i dont plan on making a network. i dont have a hub or any cables right now and i really dont wnat to go out and buy the wrong one and have to go back. i have dsl though the one box. the connectoins i have on my new comps are usb, newtwork, modem ieee 1394 dvi video, video connector
