My main data-logging machine has six serial ports (2 on the mobo, four 
more via PCI adapter) and two NI GPIB cards.  I also have serial cable 
strung all around the lab.  I can use USB, but a relatively inexpensive 
serial solution is easier to drop in and offers more flexibility (for 
example, use a $150 Soekris single board computer as a logging device as 
well as super-duper time server; it has two serial but no USB).
