Dip

From Linuxhelp Wiki

ccodom Dip handles the connections needed for dialup IP links, like SLIP or PPP. It can handle both incoming and outgoing connections, using password security for incoming connections. It has a command mode (an interactive program to set up an outgoing IP connection), dialout mode (interprets chat script to dial out and open an IP connection), and dialin mode (login shell for handling incoming IP connections, as in dialup SLIP and PPP connections).
