Hello (I'm back!)... :) I was wondering, since so many of you have used PICs to interface with a PC, if anyone has (example) code of how to use the parallel port under Windows (98). I've tried the assembly thing (mov al,data mov dx,port out dx,al) but it only seems to allow me to transmit 16 bytes, after which it just stops transmitting altogether. My device is not being over-run or anything like that... It just seems to stop transmitting. Anyone got some suggestions? :) TIA, -- ~Keith tsk3000@Prodigy.Net http://pages.prodigy.net/tsk3000/ ICQ UIN 15590177
