Programming Cable The UART chip for this radio is not in the cable, but rather the radio. The chip used is a CP2102 which uses standard drivers that will download from the internet. The programming cable may look familiar as it very closely resembles that of a my Motorola cables.  Although the pin out is the same and the structure is virtually identical, a Motorola cable can be used, but requires a little shaving of the plastic. If you're not handy with a Dremel tool, I would just purchase the proper cable from Radtel.
