tgp1994 Posted November 25, 2012 Posted November 25, 2012 (edited) Hi everyone,I know this sounds like a bit of a strange request, but I was wondering if it may be possible to get two machines to communicate/network over their modems while being directly connected with a standard RJ-11 phone cable?My reasons are fairly simple (albeit convoluted): To get a very old machine (with no ethernet port, and a crappy wireless card) to share my internet connection with a laptop, which just so happens to have a built in modem. That laptop is then wirelessly connected to my home network.I'm sure some of you are screaming "Do something else! Buy a network card!" But alas, I am cheap, and I think it would be cool to actually get this to work. I realize that connecting two computers with an ethernet cable may not be exactly the same as connecting two computer's modems, but I feel that since networking can be done over a modem, then why not to another modem?I'm just hoping that there may be some super hidden but really cool trick/hardware that allows for this. Either something that emulates the handshake occurring between a machine and an ISP when a dialup session is established (virtual phone network, anyone?), or some way that can somehow establish a serial connection over the modems.Thank you for any help!

bphlpt Posted November 25, 2012 Posted November 25, 2012 Google and look up "null modem". It is essentially one piece of what you are talking about. Connecting two computers directly through their modem connections, typically RS232. The two computers will then be able to communicate with each other, but to share an internet connection is a whole different problem that I don't know if you will be able to solve.Cheers and Regards

I'm not sure if that applies to me, I'm just trying to connect these computers with a phone line. Serial isn't really an option :\I'm just hoping that there may be some super hidden but really cool trick/hardware that allows for this.

It almost seems like I need that in order for these computers to pick up that automated process of establishing a connection. I was messing around in hyperterminal and managed to get my machine to start playing familiar sounds (with the ATA command), although getting both computers to do that didn't really seem to do anything.I tried following the guide referenced in that article, although I'm not really sure what program on the "server" machine is supposed to handle the incoming call...
jaclaz Posted November 27, 2012 Posted November 27, 2012 I tried following the guide referenced in that article, although I'm not really sure what program on the "server" machine is supposed to handle the incoming call...The modem must be put in "waiting mode", it is described in the article (still AT commands), it may work or may not without the ring/line voltage, the rest is "connection wizard"http://www.maturion.de/dreamcast/mterlouw/inconect.htmon 9x it is "Dial-up server":http://www.maturion.de/dreamcast/mterlouw/configpc.htmjaclaz
submix8c Posted November 27, 2012 Posted November 27, 2012 BTW, Serial is a route (but slow), and Parallel is also a route. They both are Direct Cable Connect (same concept), Parallel being "faster". Just in case you don't get the Modem thingy going. BUT, by all means, keep up the experimentation. If it DOES work, we'd all be interested in the process.
Ponch Posted November 30, 2012 Posted November 30, 2012 You do realize your "crappy" Wireless card might still give you 200 times the speed of that phone line, right ? That might get relevant ...later.
tgp1994 Posted January 15, 2013 Author Posted January 15, 2013 Hi folks,Sorry for the very late bump, but I'm afraid I have some bad news... I won't be able to continue working on this project, as I no longer have access to appropriate hardware I'm sorry to let you guys down... I sure as heck wanted to get this working. Maybe I'll be able to pick this back up later, or someone else might make a break through Thanks for the support, everyone!
