There might not be a network available, and it is unlikely that you lug a serial cable with you when you travel. If both of you are using notebook computers, the best solution is to use infrared to send the files.
When two computers are within communicating range of each other (with

application allows two computers to exchange files using infrared.
You can use this utility at the command prompt. To see a list of

Exchanging files between computers using infrared is similar to doing so with a Pocket PC; this is demonstrated in the following section.
Most Pocket PCs contain a built-in infrared port for communicating with the outside world. Using the infrared port, you can transfer files from the Pocket PC to the computer (and vice versa) without using a cable. Figure 7-4 shows the iPaq 3870 with the infrared port located at the top.

When you align the infrared ports of both the Pocket PC and your computer, Windows XP will inform you that a Pocket ...
