You guys should know that you don't really have to fool with putting an adapter into a box or fitting the connectors to it. This FT232RL-based one in the photo is available for about $8-9...

I use this one, case included. Construction time: about 5 minutes total for 12-pin, about 15 minutes total for 16-pin version....

If you ever want to give that utility a try, the changes will not take effect until the unit is unplugged from the pc and plugged in again (rebooted). It seems that the internal hardware gets set at...

The "another converter" flipped the polarity. Most involve the use of an RS232 IC or a couple of NPN transistors. The TTL-to-USB does not invert the signals to make it RS232 compatible. When I placed...

The FT232RL will only work if the TXD and RXD pins are inverted, since standard RS232 is already inverted from TTL. Fortunately FTDI included that fix in their programming utility. It's a no-brainer...
