Using an analog modem for ICS through a pc's Ethernet

[Alan Wells]

I have an old Kenwood media server that uses Openglobe CDDB. It connects to the Internet a few ways. USB Ethernet adapter, HPNA, and modem. The HPNA connects to the modem port on the Kenwood.

Ethernet compatibility is limited to a few Linksys and D Link adapters that use a Pegasus chipset. The OS is embedded.

So far using the USB adapter that I have through my router has been spotty at least. I have no POTS service.

The question arises do I purchase a HomePNA adapter and go that route or buy another compatible USB Ethernet adapter (IF I can find one) from the auction sites and take a chance?

Since I have a box of modems, would there be a software method to share Ethernet from my Win 7 64 pc to the modem? Or would there be a way to emulate an HLNA with an internal pci modem to let me make a modem connection to Openglobe?

If a modem could be used to dial out, are there links to show setup, how the modem would detect a dial out from the media server, authenticate, make a connection etc Just like a remote server would if I had POTS? All I would need is to do is take the modem off the hook (atdt) and pass Internet through.

I have scoured the 'net and I have a whopper of a headache. Anyone wish to offer suggestions? I'd really like to see if emulation or possibly using a modem is an option to connect to the Internet through my pc.

Thanks beforehand,

AW

Is the modem adapter a standard db9 or db25. Next do you have a db9 serial connection on your pc.

You should be able to use a null modem cable and hook these back to back. This is very old school method of networking. If you PC does not have a serial connection you can get USB-serial cables.

Then you can use ICS since this is what it was designed for. People use it do share wireless and stuff but it was deigned to share a modem dial up connection to the internet.

The computer does not actually know if there really is a modem connected. The computer will not care but some devices need things like carrier detect set high so your null modem needs to do that as well as cross all the CTS RTS DSR etc etc signalling. Most null modems do this. It is also no very hard to get a db9-db9 cable and cut it in half and twist the proper wires together....then again i have made lot and lots of these many years ago.

The serial ports is not very fast though most things do not go above 192k (yes kilo not mega).

Hey Thanks!....but
The Kenwood Entre has a built in dial up modem. Ports for external comm are RJ11 for dial up and Hpna. Hpna is also used through the RJ11 port. There are 2 USB ports to use a USB adapter. The adapters used are specific and from lhe compatibility list most use an ADMtek Pegasus chipset.

With that given, I havent found much on Hpna functionality but suspect traffic is "always on" as opposed to an analog modem which goes off hook, dials out from the pc to the server

The Entre uses ancient technology, I know. But dummy it down and think as if you would wish to connect a fax machine to your pc modem and have the modem ready to connect to a remote fax when you send to a particular number. In this case the Entre dials out and connects to the Openglobe CDDB. I can get the web page of Openglobe and it says it's for CDDB connections.

Obviously you really shouldnt be able to connect to a POTS fax machine from a pc modem attached fax machine, but I hope you get the idea. I see links for modem pooling. Something like that.

I would like the pc modem to supply Internet traffic (like when you dial internally connceted to POTS), but from the pc Ethernet connection, to the modem, and to the Kenwood internal modem. To simply wait for a dial out signal from the Kenwood (or take the pc modem off hook) and route Internet traffic through it.

Ideas?

We used to build phone line simulators with batteries and a couple of resistors but it has been so long I forget how I actually did it. I am sure they sell the devices. You should then be able to attach a modem to your computer. They used to make routers that you could connect a modem to but its been so long its hard to say if those still exist.
