Finally received my USB TTL cable from Amazon, $4.72 including shipping. Color codes are below,
Red --> TX
Green --> RX
Black --> GND
White --> (not used)
Using driver on first post, Windows 7 with HyperTerm on first post. Unbricking my PBO in few minutes. I didn't even connect the White wire. Thanks guys.
People having trouble, if you don't see anything coming on the terminal, most likely your connection is wrong, use multimeter to figure out the color codes on the wires first, each type of cable could have different color codes. Good luck.
