Carrier dropped and ppp exits on SIGHUP.

IMHO, exit on SIGHUP is bogus.  This should be a config option but
no time...

Change signal(SIGHUP, Hangup); in main.c to signal(SIGHUP, SIG_IGN);

Or delete both occurances of this snippet in modem.c:

    if (!(mode & MODE_DEDICATED)) 
      rstio.c_cflag |= HUPCL;
