Dynamics RMS for Retail - EFT POS Integration -- 2

the EFTPOS sample code in Dynamics rms for Retail to build a working module to integrate EFTPOS pin pads with the Rms POS client? I am keen to get an estimate on time required to do this. We are using an Australian bank with locally developed gateway ie. Cba Bank and PCEFTPOS payment gateway. The pin pad is Ingenico ipp350. I have attached the current files that we use and as we have upgraded to Windows 7 64 bit machines these files no longer work Regards
