I am making a project with a microcontroller that interfaces to the computer via a 9-pin serial cable. Can I get a 9-pin serial port that attaches to a solderless breadboard anywhere?
 
Surely can,

You dont need the majority of the pins if your only using the connector for UART

  • Pin 2 - RX data for PC
  • Pin 3 - TX data from PC
  • Pin 5 - Common Earth

Wait, another question. You were right, I only needed pins 1-5, but the manual of my microcontroller says I need to directly connect pin 6 (DSR) to pin 7 (RTS) Do I need to do this? If I do, the parts from futurlec look like it only includes pins 1-5, so that won't work.

The PCB adapters from Futurlec do include all 9 pins, the angle of the photo is bad.

Depending on the application (and the programming involved), generally you don't require the other pins.. Consider this project I did a while ago: **broken link removed**
