cat /dev/input/input4 No such file or directory cat /dev/bus/usb/004/004 Displays some interesting characters Most of the new /dev entries do not have any response or are links to the other /dev entries. cat /dev/hidraw3 displays the magstripe data! I think we have a winner. Is there anything special I need to know about or do differently reading directly from /dev entries with Perl as opposed to reading a normal text file? Thanks for the help!
