modem problems

Mark Corbelli

I finally upgraded from WinMe to XP Home yesterday (Best Buy has XP Home
upgrade on sale for $39 after $50 rebate). I did a clean install and loaded
up all my software and backups. Everything works fine except I can't get my
modem to dial to save my life. I have tried COM 1 and COM 3, I have checked
all hardware for conflicts, I've made sure all the ports and the modem are
enabled. I have played with the transfer rate, but no joy. I don't think the
modem is even dialing, as I can't hear anything happening, yet Windows says
all my devices are working properly (apparently they aren't working together
properly. No matter whether I use my Juno set-up software, or start a new
connection manually, when it say's "dialing" nothing is happening. And when
I click "cancel', it hangs my computer. The modem worked fine before I
installed XP . What else can I try?

Is the modem an ISA internal? Plug and Play mother boards have trouble
detecting and installing ISA or legacy devices.

First thing, make sure if possible, both Com1 and Com2 are disabled on the
mother board. Do this in the BIOS settings at startup.

Boot into XP safe mode and remove all modems installed from Device Manager.
You may also remove COM1 and COM2 from Ports.

Restart the computer and let Windows XP do its thing. If it does not find
you modem, in the control panel select Phone and Modem Options and then
click on the Modems tab. Click Add and see if that finds you modem.

The last thing you can try is to make sure nothing else is using the
interrupt of the modem. (INT 04 - 03F8-03FF -or- INT 03 02F8 - 02FF). You
can list devices by connection type in Device Manager by selecting View.

Did this help you Mark?

I don't think it's an ISA modem because it plugs into a PCI slot. This is
the same MB that I was using before upgrading to XP so I'm not sure if it's
a MB issue. I was looking at Kelly's Korner and there was something about
not matching the COM port number on the Device manager with the COM port
number on the modem, which is confusing. This may be the issue, however, as
after the upgrade, the modem was set for COM 3 and the Ports on device
manager only showed COM1 and LPT1. So I changed the port setting of the
modem to COM1. That didn't work either, so I tried both at COM 3. Maybe I
should have left it at COM 1 for the COM port and COM 3 for the modem? There
is definetly a conflict or why else is it hanging my computer when I try to
exit out? I'll try some of these suggestions you have made when I get back
to work.

Try following the instructions given earlier and things will work better for
you. This applies for any modem PCI/ISA.

Its worth a try!!

What I would try is to remove all references to the modem from
Device Manager, shut down and unplug your computer, take out your
modem, reboot, shut down and upplug again, install the modem,
reboot, and see what Windows XP makes of it.

I tried what you said. I can't see anywhere in the BIOS to disable COM 1 or
COM 2. There is no COM 2 in device manager, only a COM 1. I tried booting in
safe mode, deleting the modem, etc. Windows installed the same driver with
the same result. I checked on the interupts. The interupt for the modem was
0000C400-0000C407 and the interupt for the COM 1 port was 000003F8-000003FF.
I couldn't see any other devices with these exact same numbers.

I did notice, however, that both the modem and the video card use IRQ 11. Is
this OK? If not, how do I correct it?

Thanks

IRQ Sharing shouldn't be an issue. In BIOS setup many times the
COM ports are controlled/described as Serial Port A & or B.
Normally found in the Advanced or Peripheral Control sections.

You may need to get XP drivers for you modem, or replace it
with one that is compatible with XP if no drivers are available.
So take a look at the driver CD, does it have drivers for Win2000/
XP ? - ME ones won't necessarily work.

Actually, I never installed drivers from a CD. Once XP was finished, the
driver was already installed. In fact, I can't be sure the modem listed in
device manager is even the one in the computer, as the card has no distinct
markings. I'm only assuming that XP is automatically detecting the modem and
installing the correct driver. In any case, there is a driver installed and
I didn't put it there. There is no yellow exclamation point attached to it
either. As far as a driver CD, I've long since lost this. It may be a good
idea to just buy another one, as they are usually dirt cheap. On the other
hand, if it's not the modem, I don't want to just throw money away either.

Yes, I do remember serial ports. I guess tomorrow I'll try to diasable them.
However, what does this do?

the key will be if XP identifies you modem correcty I think - not
merely a "generic modem", but as you realise they are cheap enough
$25.00 here [AUS] for a decent Rockwell chip based one.

I agree. For the cost, if what I recommend does not work, which it probably
will, then buy a modem with a brand name chip set like Rockwell.

Apparently this is a common problem. I took the modem out and it's a
conexant. I went to their site and under FAQ's there is a topic exactly
identical to mine. There is a fix in place (downloaded an .exe file). I'm on
my way back to work right now to see if it solves the problem. I'll let you
know.
