Mike's notes on the modifications: - renamed error() function because of namespace problems - removed calls to the exit() funciton - removed extra files from the pppd source directory - defined pppd task constant values in rtemspppd.h - modifyied example code to get actual tick per second value - placed the pppd 2.3.11 man page file (pppd.8) into the pppd directory * pppd/cbcp.c, pppd/cbcp.h, pppd/main.c, pppd/ppp_tty.c, pppd/pppmain.c, pppd/rtems-ppp.c, pppd/rtems-ppp.c: Deleted. * pppd/pppd.8, pppd/rtemsmain.c, pppd/rtemspppd.c, pppd/rtemspppd.h, pppd/sys-rtems.c, pppd/utils.c, pppd/example/Makefile, pppd/example/README, pppd/example/init.c, pppd/example/netconfig.h, pppd/example/ppp.conf, pppd/example/pppdapp.c, pppd/example/system.h: New files. * modem/ppp_tty.c, net/if_ppp.h, pppd/Makefile.am, pppd/README, pppd/STATUS, pppd/auth.c, pppd/ccp.c, pppd/ccp.h, pppd/chap.c, pppd/chap.h, pppd/chap_ms.c, pppd/chap_ms.h, pppd/chat.c, pppd/demand.c, pppd/fsm.c, pppd/fsm.h, pppd/ipcp.c, pppd/ipcp.h, pppd/ipxcp.c, pppd/ipxcp.h, pppd/lcp.c, pppd/lcp.h, pppd/magic.c, pppd/magic.h, pppd/options.c, pppd/patchlevel.h, pppd/pathnames.h, pppd/pppd.h, pppd/upap.c, pppd/upap.h: Modified.
