[Skunkworks] POS & ETR Connection

Hi Skunks, I need help reconfiguring a POS system to an ETR. The PC crashed and following reinstallation of software, the link has been problematic and only recently full stopped working. This is for a school uniform shop in Kitengela and as the high season approaches we'd prefer not to go back to manual receipting, so assistance in the immediate future would be most appreciated. Please get in touch off list. Thanks! Majala +254 722 167 067
