I have a new computer with an ASUS P5N32-SLI motherboard. This motherboard
has no physical parallel ports at all. It seems to be a new trend. XP Pro
was installed. I now need an LPT1 to interface to some speciallized IC
programming equipment, so I added a MosChip Technoloy SY-PIO9835-2S1P PCI
card which has 2 COM ports and 1 LPT port. When installation was complete,
the parallel port was added as LPT3. The specialized hardware cannot
communicate on LPT3, so I need this physical parallel port to be reinstalled
as LPT1. In the Device Manager under Ports (COM & LPT), only COM1, LPT3,
COM3, and COM4 exist. The latter 3 are from the MosChip Technology PCI card.
LPT3 cannot be changed to LPT1 on the resources tab because the "Setting
Based ON", "Use Automatic Settings", and "Change Settings" controls are all
greyed out and inoperative. Is this because all 3 LPT ports are though to
exist already, so you can't change one? Under Printers and FAXs, the
properties for any given printer allows assignement to any of the 3 parallel
ports LPT1, LPT2, and LPT3. This suggests Windows thinks they exist. A
regedit search of the registry keys shows that all 3 LPT ports are listed
under HKEY_LOCAL_MACHINE >> Software >> Microsoft >> Windows NT >> Currect
Version >> Ports. I do not know why LPT1 and LPT2 are listed here if they do
not exist. Is this why the fisrt real LPT port installed itself as LPT3?
How should I correct this? Should I uninstall LPT3, then delete the LPT1 and
LPT2 registry keys from the registry location above, and lastly reinstall the
new physical LPT port? Will this make it come up as LPT1? Are there any
downside risks or considerations to doing this? Thanks.
