I get Could not grant slave pty on telnet/rlogin

In Solaris 8 and later you must make sure you have syseventd/devfsadmd
running or the automatic pty node creation does not work.

In older releases this probably means that you changed "pt_cnt" but
didn't reboot with the "-r" flag. To recover, run "drvconfig; devlinks".
