I have a radio automation system written using c++ and qt3. It was compiled using suse 9.1. I need to have it compiled using qt4, suse 11.4, kde4. The software uses the low order nibble of the parallel port to control peripheral pieces and the high order nibble to control the software from external devices. I need to be able to use a usb to parallel converter for this control as the type of computer I would like to use does not have a parallel port available. Secondarily I have items that need doing on a continuing basis which can be addressed once the conversions is complete and successful.
