My new Dell laptop has only USB ports, so I bought a Keyspan port 
replicator that has a serial port, a parallel port, and two more USB ports.

I was able to get my old HP printer working through the Keyspan parallel 
port, but not the (even older) IBM scanner. More significantly for this 
group, I was not able to get Linux's Xlog to communicate with the Orion 
II through the serial port. (This might be a Hamlib issue.) I just 
couldn't find a way to specify the proper port.
