Does this product support non-PPP/SLIP connections? That is, can I dial into the RASFinder using just a terminal connected to a modem? Once connected, will I get a command line interface (CLI) prompt from which I can initiate a telnet session?

Yes, our RASFinder supports dumb terminal dialin. You will get a menu when you dial in with a dumb terminal and from the menu, you can select telnet to a host.
