How does it cost $5? In the simplest case, you need a few wires from the
parallel port.
The microcontroller on the C2N232 can be programmed without any special
hardware. You'll only need to short the RESET line to ground. In the
successor version, which Nicolas Welte is working on, the RESET line
will be driven from DTR, so even closing the jumper is not necessary.
I wrote my own programming tool, "cisp". It's available from
http://www.zimmers.net/ as well as my personal page
http://www.iki.fi/~msmakela/software/cisp/.
Sadly, both sites have been unreliable in the past few days,
so please be patient.
