I need to write an LPT management program, but I've got no LPT port on my computer. Is there any software for emulating it?
One solution for a LPT emulator is the VMware player, which you may find available for download at http://www.vmware.com/products/player, and on which you may access more information at http://vmware-player.software.informer.com/3.1/.
Another option is the Serial RS232 and RS485 analyser, which you may download from https://iftools.com/analyzer/index.en.php?gclid=CKPOkLz0xa4CFYRa3wodJA0qUg.
