The pppstart(1M) function enables client PPP operations on the C5 system. See Chapter 11, Setting Up PPP for details on configuring a C5 system as a PPP client. In order to use PPP, you have to embed the pppstart process into the C5 system image.
pppstart(1M) uses pppstart(2K). See the sysLog(2K) man page for examples of how to read the log.
