Sun Remote System Control (RSC) User's Guide

ppp_remote_ip_addr

Use this variable to specify the IP address for the remote node during a PPP session; use standard dot notation. If this variable is empty, RSC expects that the remote node already has an Internet address assigned for the PPP session. The default setting is 0.0.0.0 (empty). Changes to this variable take effect on the next PPP connection over the RSC serial port.
