How do i use Dial up modem to view remote panel?

[Vikask]

Hi all,

I want to view remote panel of my LV application using dial up modems connected to each PC using a phone line between them. Can Any one guide me Further?including modem specs.

To view a remote front panel you need the IP address of the hosting PC, so once you connect (assuming you get automatic addresses) you need to find the IP address of the host (should be in the control panel>>network connections or modems or something similar, depending on which OS you're using) and make sure you can talk to it from the other computer. You can do this by running a ping (in windows that would be

Start>>Run>> ping x.x.x.x (that's the address) -t ) 

and if they can talk you will see lines telling you that some packets were sent and how long it took them to get back. If you can't ping the host, you probably need to set the subnet mask in your connection settings to 0.0.0.0 and check to see that you don't have a firewall blocking the communication.

Once you have the IP address and manage to ping the host, connecting to the remote front panel should simply be a matter of using the correct URL, as described in the help.

tst's description works for systems that have the internet sitting in the middle, but it sounds like perhaps you are wanting to dial directly into one computer from the other one, yes? If so, you'll need to define and implement some sort of protocol for transferring the data back and forth across a serial link.

In terms of modems, nearly any modem should work. To talk to the modem, you'll have to know AT command codes.

How many values are you actually transferring?

Another option would be to "RAS-in".   See this for details on RAS (Remote Access Service):

Has Microsoft fixed RAS yet? I was building a system in Canada a few years back that was depending on a RAS connection and about once a day the connection would hang and you had to power-cycle the PC to recover--not real convenient when the system in question is 20 miles north of Nordegg, Alberta!!
