Cardinal jumper settings?

I have a Cardinal Technologies modem, model #020-0461, according to the cool white sticker.  Apparently Cardinal was bought out by Hayes, which in turn declared Chapter 11.  As a result, there are no online manuals or other resources that I can find for this modem.

I need a diagram or list of the jumper settings for this modem.  I'd prefer to hard set it to COM2, IRQ3, but am willing to try plug and pray if need be.

A company named "Modem Express" bought the Hayes assets from the bankruptcy trustee.
So, take another look at the "new"  http://WWW.HAYES.COM

The Cardinal modem that I have purchased have been *VERY*
similar to the US Robotics Sportster V.90 modem,
i.e., Cardinal purchased chip-sets from Texas Instruments,
just as USR does, and Cardinal licensed the X2/V.90 technology from USR.

So, if the jumper-settings are not silk-screened
onto the modem, then just "pretend" that you have a USR modem.

Of course, I have to try it...:)  I did discover that the modem I have is a 28.8 anyway, so chances are I'm going to be buying a 56K to actually use.  But I will get my hands on a USR manual and check the jumper settings and let you know what I find out.

I looked at one Cardinal 28.8 modem,
and the jumper-block was clearly labelled:
(COM1, COM2, COM3, COM4, IRQ3, IRQ4, IRQ5, IRQ7, IRQ9),
and it was set to COM4/IRQ3.

The modem I have has an A0, A1, 4, 5, 2, 3 on on side of the jumper block.  The other side has 1,2,3,4,5,6.  Those are the only markings on this one.

> modem has A0, A1, 4, 5, 2, 3 on on side of the jumper block ...

So, you have a two-by-two grid, using A0 and A1,
and the two nearest pins,
which gives you four combinations (COM1 through COM4),
and you have to close one of IRQ4/IRQ5/IRQ2/IRQ3.
