In principle you can, just set a pointer to the hardware address with which you wish to 'talk'. but, imho you'd be much better off using one of the existing drivers to do all the grunt work for you. > Or am I going to have to get to know c? Yes, start off here. ftp://ftp-svr.eng.cam.ac.uk/misc/sawtell_C.shar reported to be still one of the best "Starting out with C" tutorials on the 'Net. The prose is digestable. -- C. S.
