Make sure you wear your safety glasses when clipping leads!

6. Solder 12" wires to the solder cups for Pins 3, 5, and 8 of the DB9
   connector.
   The location of these pins is shown in Figure 7-10. Although the manu-
   facturer prints the pin numbers next to the solder cups, you might need
   a magnifying glass to read the pin numbers on the connector.

Be sure to heed all the safety precautions about soldering that we list in

Chapter 2. For example, don’t leave your soldering iron on and unattended.

And just in case a bit of solder has an air pocket and pops, wear your

safety glasses!
