Like any TCP network sniffers are usually the best method to see any traffic, especially dialup.
You can however use PGP or another means of encrypting sensative information.
Some connection specific details are required, but there are tel. adapters you can connect to encrypt communications on the line. Both ends would require this.
But like any encryption means, its not secure unless
you fill a safe with cement, put the server in the cement and drop it in the middle of the deepest ocean ;-)
If someones dedicated, they'll get whatever it is you have. Regardless. But, hey you can try.
