/* The script sends the dial string to the modem and then logs into the */
/* terminal server using the username/password. It then issues the SLIP */
/* command to start SLIP, and parses the resulting output to determine the */
/* appropriate addresses to use. Lastly, it issues ifconfig and route */
/* commands to configure the OS/2 system appropriately. Note that the */
/* configuration assumes a class C netmask for the SLIP interface. */
