A far more geekier solution would be to use an arduino board and a ttl 2
rs232 chip and make your own serial converter using a couple of gpio pins.
Of course you'll have to write some kind of kernel driver for Linux to
interface with the thing. :)  but think about how much fun it all would be.

On a serious note, serial communications will likely never go away
especially in embedded environments.
