I have a parallel port (25 pins) 89s51/52 programmer.. I have an IBM R51 laptop.. It has a printer port in it.. But whenever i try to 'program' any hex file using SPI Flash Programmer.. It displays a msg "No response from uC".. I have purchased it from a local shop.. Its working there (the guy has a desktop).. But it wont run on my laptop.. Help????
Is this due to different types of printer ports on his desktop and my laptop?? How can i resolve this issue??
