I was told about a mechanism called laplink that would hook a desktop to a laptop. The problem with it seems to be that it needs both a serial and parallel port connection on both machines. I have a serial port free on the desktop, parallel is taken by the printer, not so serious a problem necessarily, but the laptop's serial port is taken by the dectalk express, something I can't do without, as I have to know what's on the screen to tell it to transfer, and to know when it completes. I have a modem in one pcm slot, and something else in the other, not sure why it's there. Is there a way to get a third slot, so I can put in another serial port to satisfy laplink, and is it necessary to use the serial connection at all?
