COM ports not working XP dual boot with 98

[Guest]

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

Hi, I've been all over the web looking for a solution to
this problem. My COM ports (COM 1 and COM 2) are listed
as having reported problems (Code 43). I have uninstalled
and reinstalled them. I have uninstalled my modem and
tried previous. I do not see any IRQ conflicts. My BIOS
shows the COM ports as enabled.

I have a gut feeling that this problem has something to do
with my dual-boot setup, Windows XP and Windows 98, each
on a separate hard disk. 98 sees the COM ports as working
properly, but XP disables as soon as they are recognized.

Any information or hints would be much appreciated!

thanks

David

If you are not using the com ports they should be disabled in
the BIOS. Modems that are not winmodems are usually
COM 2 IRQ 3. PCI slot modems will come up with com 3
or com 4, depending on the drivers.

my modem sets itself to COM 5 IRQ 3. I'm not sure whether
it's a PCI modem or not. I'm pretty sure it is not a
WinModem. Would that cause a problem?

I tried disabling one of the COM ports in the bios, but
there was no change - the other COM port comes up as
having a problem.

Are you saying that if I give up on the COM ports I should
disable them in the bios?

So far I have had no luck trying different combinations.
The only thing I haven't done is remove the modem
altogether, though it doesn't seem to be causing a
conflict.

I'm about to buy a USB adapter for my device (palm pilot)
and just say to hell with it! Is there any way I can save
these COM ports?

thanks

I've got a dual boot win98/XP pro machine and have no problems
with the hardware comport on the mother board. "Hotsync" types of
applications for the likes of palm pilots and such are notorius
for messing up the com ports. Uninstall any that you may have
loaded on your machine and try rebooting. I'd also try removing
the modem and rebooting. XP does wierd things with the com ports
that only XP understands. I've also got a USB to serial port
adapter gizmo and it works just fine.
