why won't my new installed modem work?

I have an ibm ps valupoint 1992 vintage computer. model M00, machine type is 6384.   i wanted to upgrade to a faster modem.  i've tried 3
different modems, including a USR non winmodem, and no matter what
I do, i get either "modem not found" or "another dial up networking connection is using this port.  I've tried com1, 2, 3, and 4, with the ports
first enabled, and then with each one disabled with the same results.
this is also pcdos. what am i doing wrong?
I have windows 95 installed, & i've tried removing it both in setup and in control panel with the same results, & on bootup, it finds nothing, is there something that has to be done on the
motherboard?

Did you remove the old modem? had to ask to be sure.
Did you go into Device Manager and remove all listed modems from there?
Also do the same from the "modems" icon in the Control Panel.

When you bootup does Windoze find the modem? or does it find anything, like maybe an unknown device?

Wait?? Are you only running DOS on this machine?? Or am I misreading your question?

Winmodems will only work with Windoze.

Please post new comments in line with the posted comments, don't use the edit question option, this make the posted comments look stupid and hard to follow.

Did you use the "Add new hardware" icon from Control Panel??

rayt333Commented:
OK let work with the Winmodems first, did you try installing the software first and let the install program seek the modem? This sometimes works.
I am wondering about the system whether or not the PNP will work with it?? Maybe not

I've tried it with first installing the
software to no avail, it doesn't find
a com port, although com2 irq3 are available, then tried installing via
modem, then loading the driver from
floppy a.  also tried pnp, it finds
com 1 or com2 if i disable each individually, but gives the same original message. the modem has settings on the modem, i've tried all
settings to no avail.  when i look at msd, i find that com 1 shows a 2400 baud modem, but i'm loading
a usr modem sportster 33.6k with the right driver, internal 33.6k

Try installing it as COM 6.  Make sure all the COM's are available in the BIOS.  I've had it happen to me plenty of times.  The Windows recognizes it and installs it , no problems, except one, it doesn't work.  I've had to download another driver from the internet for it.  Also, make sure it takes the right driver.  Sometimes when you instal a driver, even with the manufacture's driver, it get's installed wrong. Also check to see if the driver is "onbaord" as this may solve your problem.

This modem is the best choice for an older computer which is not "plug-and-play" capable, and which is using DOS or Linux or OS/2 Warp.

Try the USR modem again.
Set the jumpers to COM2 and IRQ3,
and either:
 - disable the motherboard's COM2 port,
 - if you have an add-on card to which the ribbon-cables for the external COM1 and COM2 connect, then set the jumpers on this add-on card to disable the COM2 port.

*   Try a phone no. with Phone dialer. Whether it is dialing or not?

*   May be some .dll or .drv files used by the com ports corrupt.  i.e. Serial.vxd or some other files required for COM port.  Try reinstalling Win95 over it.  Donot delete old files.  During installation if it asks whether to overwrite the old files with new ones, then give Yes.

There is a problem with win95,take the modem out from the computer, then operate the computer, make sure to remove all instalation of modem on it, then shut down and return the modem, when you'll turn on again the windows will recognize that there is a new hardware and will ask the software for her
