Making Win2000 rememver my modem even when it's turned off.

Hi!

I have an old external serial 33.6 US Robotics modem.

If it is turned on when Win2000 loads then everything works OK, but when it is turned off, then it is not recognized, and I have to run Add/Remove Hardware in order for windows to see it.

Can I make Windows assume that the modem is connected even if it is not turned on?

Thanks!

I'm not absolutly positive, because nothing is impossible, but I would say "NO" on having the OS find it when it's off.

You can convert the serial cable connection to firewire or usb. The cable will be over $15.

But why would you be using a serial 33K? Is this an older laptop? 56K internals are $2 to $5 used, and free new ones if you watch the rebates.

You Can go to a DOS prompt after Win2k has started and get the serial device recognized but it's "IFFY" based on the serial device card capabillities. And the ADD/REMOVE trick is probably faster.

Thanks.

33K is enough for now, (as far as speed is concerned), becouse I use internet mostly for mail and text. I will buy a 56K modem soon, but it will also be serial becouse of the following reasons:
- Both USB ports are already used, and sometimes they are not enough for USB devices that I already have.
- I'm having problems with PCI. I have 2 cards already and when I add new card to it, everything starts behaving strange. I think PCI controler died, becouse only 2 of 6 PCI slots work, and they are already used.
So all I have left is Serial port.

It's an old desktop P2 - 400, and any axpencive invesment is not an option becouse I'm planning to buy a new one in a few months.

What do you mean by converting a serial cable to USB? Will this make serial port behave like USB or will it allow serial modem to connect to USB?

I asked this question becouse I think Win98 can recognise a modem when it's needed even when it is turned off on startup. Although I'm not sure about that becouse it's been a long time since I switched to Win2000
but I don't remember having souch problems on Win98.

I thought maybe someone knows some trick which will tell windows to automaticaly search for modem when it's needed, or to remember it allways without searching for it on startup.

The cable converts a DB9 serial plug (RS-232 ) to USB. But the cheapest I found is 12" long @ $27. The cable has a chip in it with a USB serial code identifying the serial device.
 
If your out of USB slots, you can get a hub for $5 to $9 now.  But thats a total $36 investment. Cheaper to find that same mother board and replace it. An old P2-400 board can't be over $20.

Why don't you just leave to modem on all the time and save some money? It won't hurt it and they draw minimal power.

Here's why USB works and Serial doesn't.

Each USB-COM device has a unique serial number inside that Windows reads and uses to remember which driver and what COM port number to use for that specific device. This means you can set one unit to be COM-52 (via Device Manager) and another as COM-3 and they will remain that way even when the devices are unplugged. Windows considers a COM # “in use” even though the corresponding USB-COM device is not plugged in. Thats why when you plug in a USB device with Winndows running, the device initiates that response. You can override that with device manager under USB's. You cannot override Serial in device manager because windows does not consider serial in use unless found at boot.

Dont give up, everything is possible. I may be wrong or someone may have the answer in here.

Thanks.

I'll leave this Q open for some time, maybe someone thinks of something.

If it's not possilbe to make windows remember my modem, then is there some 3'rd party dial-up manager which communicates directly to COM port?
Without the need for Windows to "see" the modem?
