I suggested it because you said you wanted to run LCDHype in the NT+ environment. I know Linux but very little about Wine - the programs I need to run with it are Win 95 programs that use a serial port and have 'just worked' apart from two problems. USB-serial adapters don't work with them, but a multi-port serial card fixed that. The programs needed to access low memory, and adding "vm.mmap_min_addr = 0" to the end of /etc/sysctl.conf fixed that too. In particular, I haven't tried writing code to run under WINE. I think you'll need to write a test program or two in order to work out how to use that DLL. I may end up battling the parallel port soon since I need to port a Win 95 CAD package over. It uses a parallel port security dongle and can drive an HP plotter via a serial port. Martin
