I've got one computer that has an ethernet port and another that has a data port. Is there some kind of adapter that can be used to get these two to talk to one another or is there something else that I'm missing?

Thanks for the help!

Try installing a NIC in the second PC with the data port.  Then configure the two NICs with statis IP addresses and tey will be able to talk to each other using TCP/IP.

By data port, do you mean a DB-9 serial port?  If so, here's an ethernet to serial adapter:

I found a couple of them out there, all about the same price.  You could also easily install an ethernet NIC for about $15 and use a crossover cable.

Agreed... if you can avoid using serial and parallel communications, it's well worth it.  They are slow, slow, slow!

You can get nics and crossover cables very cheap.  Heck, you can make your own crossover if you have the parts.

RA123987 -  thanks for the input.

By the way, what's an NIC? What's a TCP / IP? I follow your logic, but when I go to the computer store I want to sound like I know what I'm talking about.

Thanks!

NIC is a Network Interface Card (where you plug your ethernet (network) cable into).  You will want a 10/100 PCI ethernet card or NIC.  The port will look like a wide phone jack and is called an RJ-45 jack.  When you install it it goes into a PCI port on your motherboard, which will be about an inch or so in from the edge about 4 inches long, and be white or off-white.

TCP/IP (Transmission Control Protocol / Internet Protocol) is the standard (suite of) internet protocol for data transmission.
