I have a Dell 810. I use a software that needs to be set to LPT1 and a tool I use that uses the RS232 slot.I tried three different usb to RS232 devices and none work.
My unit shows the paralell port is turned off. doesn't give me a turn on icon
in setup. Is there a process I need to do to turn it on or replace the mother board.
Any help appricated.
