I changed the code to read:

   int             fd = open ( "/dev/termios0", O_RDONLY) ;

in all instances, but that seems to make no difference at all. I can get
input and modify termio settings, as in the previous case, but when I
hit multiple enters (or any key for that matter) before I get to the  
code,
the select() or cin.get() don't come back.

BTW It should be noted that Termios TTY channel #0, in my ecos config  
file,
points to /dev/ser0
