Newbie question : tapi Telnet using AbsoluteTelnet 15 Years, 2 Months ago  
I am building my own private network where i need to use analog telephone line to link to PC server using normail telephone line. I heard about the special USD350 modem call way2call but
Question : can we use normal 64kps analog telephone type modem with AbsoluteTelnet on both the sender and receival side of the computer under telnet protocol to send and receive data.
The reason why this has to happen is because broadband and internet is not available in some area of course the per minute charges is very high for telephone rate compare to normal internet charges.
So if possible how to set up. Do we put 2 robotic modem each on the receival and sender side ???

AbsoluteTelnet is client software only and will not work at 'both ends' of a connection.

'Telnet' is a network communication protocol that allows a client (AbsoluteTelnet) to connect to a host PC or Unix running a telnet SERVER. You must have already established a tcp/ip network connection using LAN/WAN/dialup networking or whatever. Network connectivity MUST be established before Telnet will work.

'SSH' is similar to 'Telnet' except that the whole session between you and the host is encrypted and secure. Additional features such as port forwarding and X forwarding are layered on top.

'Dialup' in AbsoluteTelnet can be used to establish a terminal session (via modem & phone line) to a host that is allowing direct dial into a shell account. Do not confuse this with the 'Dialup Networking' features of Windows. Direct dialup is less and less common these days as most host access is being done either through telnet or SSH.

I'm not sure from your email exactly what you're trying to accomplish. Either you really don't know what you're doing or you just haven't communicated it well. If I can be of any further assistance, please let me know.

I think I am looking for the client like absoluteTelnet to dial into a window 2003 server which i could excess a shell account. Do you have any idiot proof way to set that up like the type of modems to be used on both side etc.

You have mentioned that Absolutetelnet cannot work at the server end but is this provided by window 2003? Do you have the telnet set up note in window 2003 serve. I would really like to see it work pls ..

I still don't think you understand. You cannot use AbsoluteTelnet's 'dialup' feature and establish a 'telnet' connection. They are two very different things.

You have two options:

1. Use WINDOWS 'dialup networking' to establish a network between your PC and the server machine. Then, use AbsoluteTelnet to 'telnet' across the network to the server. This requires that Windows 2003 server act both as a dialup networking host (to answer the phone call from your PC) AND a telnet host (to accept the network connection from AbsoluteTelnet). I have no idea if either of these are functions of Windows 2003 server out of the box. You'll have to get that information somewhere else.

2. Configure Windows 2003 for direct dial shell access. Then, use AbsoluteTelnet's 'dialup' to dial the server and establish the connection. This is *NOT*, I repeat *NOT* 'telnet'. Even though a similar effect is achieved (shell level access), the two methods are very different. Options two is similar to the way we used to dial into a local Bulletin Board System (BBS) before the internet. There is *no* networking involved. And again, I have no idea if Windows 2003 supports this or not.

In both case 1 and 2, both the client and the server must have a modem. The type of modem is usually unimportant. AbsoluteTelnet can *ONLY* function as the terminal client under both scenarios and has *no* server capabilities

Since you're still throwing around the word 'telnet', I assume you want to do option 1. However, the 'dialup' you need to do is not the AbsoluteTelnet 'dialup' feature you would use in option 2, but rather the Windows 'dialup networking'. Once the networking is established, you use AbsoluteTelnet's 'telnet' feature to start the shell session. All you need to tell Absolute is the network IP address of the host to connect to.

Do some more reading on google and also on deja.com. To set up W3k as a dialup server, you'll need to enable and configure the 'RAS' service. RAS stands for 'Remote Access Server'. To enable telnet, you'll have to enable and configure the 'telnet' service. You'll need to do both of these things for option 1 above.

The central place for starting/stopping services can be found on the ControlPanel->AdministrativeTools->Services option of Windows. At least, that's where they are in W2k.

Hope this helps

Brian

Thanks Brian. Guess I have to try the direct dial up to window 2003 without "telnet" or "networking" What I am trying to accomplished is to allow a Point of sales PC to send and receive data to the server without internet access at about 64kbps rate of upload and download hopefully so any other ideas would be appreciated. Something like the www.way2call.com modem but can be programmable through dot net.
Thanks,

I looked at the modem. I'm not really sure from their description exactly what it is the modem does. It's not something I'm familiar with.

LOW DENSITY CLIENT BASED VOIP AND CTI SOLUTIONS
IP ENABLE ANY ANALOG TELEPHONE
CONVERGENCE DATA AND TELEPHONY NETWORKS
SEAMLESS INTEGRATION WITH ALL TAPI AND TELEPHONY APPLICATIONS
I'm a developer and this is marketing jargon. I still don't know what it does. Further reading reveals a 'developer benefits' section that promises you can integrate your applications with their product, but I still fail to understand where AbsoluteTelnet would fit into your project.

The way2home modem are used by the X10 home automation guy for the home automation. I have seen this homeseer software that can interface with the cellphone in that if you press certain number with hash key in your handphone, you can give command to your x10 compliance device in your homeseer software to switch on or turn off the light.
But it is pricy at USD299 and using this to transfer data is unproven not that i can find yet.

Why try to use this modem, then. Most computers have modems already. Just use the built-in one.

From an application design perspective, I'd design my application to use TCP/IP network protocols to transfer the data. Then, whether you're on a LAN or use dialup networking to establish connectivity over the phone, your app will still work.

Fundamentally, though, your POS PC and your server have to be able to talk to each other. Are they designed with this functionality built in already?
