Question on cables
 

What cables are needed to unlock the newer benq siemens models with the dongle software i currently use a COM to PS2 adaptor with the 2 different PS2 connections for the older style models, my normal reseller only has RJ45 A31 connecters for same would this work through SETool Box as a RJ45 adaptor as i have done with RJ45 cables on other softwares before and is the A31 the only adaptor needed for the supported new handsets or is there more.

Thanks in advance for any help you can give
