Well, actually, not the whole chapter is about this topic.  The chapter is
titled 'Terminal I/O', which is basically what you're talking about.  
Section 11.10 discusses how to disable echo without doing a 'system()'
function call.  Doing a 'system()' function call when getting the password
is not very secure.  Obviously, if you're considering passwords, security
is an issue.  Section 11.11 discusses how to implement 'getch()' the UNIX
way, i.e. without curses.  But this is just the tip of the iceberg for
this book.

Good luck.  Sounds like you're on your way...
