[ts-7000] ttyAM1 non blocking with Debian release

["damotclese" <>]

I see that there's some discussion in this forum about
setting non blocking on ttyAM1 when running the TS Linux
however I don't see anything posted about Debian.

What I'm doing is:

serial_port2 = 
    open("/dev/ttyAM1", O_RDWR | O_NDELAY | O_NOCTTY, 0);

Which I expected to be enough to set it to non blocking
however it remains blocking -- I have to hit ENTER to
read characters from the stream.

Next was to try adding this to the stream:

    int16 options = 0;
    options = fcntl(this_socket, F_GETFL);
    // Set the non block option
    options |= O_NONBLOCK;
    (void)fcntl(this_socket, F_SETFL, options);

However that didn't help -- it still blocks.

Can anyone spot what I'm doing wrong?

Thanks!
