1 office 1 pppd: Do not clobber exit codes on hangup
2  
3 When a modem hangup occurs, pppd unconditionally sets the exit status code
4 to EXIT_HANGUP. This patch only sets EXIT_HANGUP if the exit status code is
5 not already set to an error value.
6  
7 The motiviation of this patch is to allow applications which remote control
8 pppd to react properly on errors, e.g. only redial (relaunch pppd) if there
9 was a hangup, but not if the CHAP authentication failed.
