I will look to see what effect opening /dev/termios0, but most

I have seen use STDIN_FILENO directly.
Please could you point me at the eCos examples that do this?
Changing my code slightly, I now find that I now block at cin.get().
I wondering whether I am doing something wrong when changing to
canocial
mode?
char InputHandler::DoPressAnyKey()
{
struct termios ts, ots;
int c = 0;
int fd = STDIN_FILENO;
cout << "--0\n";
tcflush(fd,TCIOFLUSH);
cout << "--1\n";
You are using stdout, not the file descriptor for a /dev/termios0. I
would first determine is you are using the correct file
descriptor. When this really is wrong, nothing will work......

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
