--- Comment #123 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
does not contain the names of the signals on the FT232 PCB.  different FT232
PCBs will have different orders.  this will result in confusion and destruction
of hardware.


ft232 pin and wire colour table converted to jtag signal names:

 _________________________
| Pin # | Name |  Colour  |
|-------|------|----------|
|   1   | GND  |  Black   |
|   2   | TMS  |  Brown   |
|   3   | VCC  |  Red     |
|   4   | TCK  |  Orange  |
|   5   | TDI  |  Yellow  |
|   6   | TDO  |  Green   |
