Problem with serial port
I hope someone can help me, excuse me if my english is not perfect.
I have done a server running on the dev_board lissening on a socket and the
seriel port 1 (ttyS0). The problem is that I can't make the dev_board sending
data over the serial interface. The strange thing is that the same code is
working on the PC without any problem.
To try solving the problem I made two test application, one server lissening
on the serial port and one sending. When I start the server on the dev_board
and the sender on the PC it works, but the reversed do not.
I init the port with:
serial = open("/dev/ttyS0", O_RDWR | O_NOCTTY );
if (serial <0)
fprintf(stderr, "No, the port /dev/ttyS0 is NOT open ");
fprintf(stderr, "/dev/ttyS0 open with fd = %d\n", serial);
newtio.c_cflag = B38400 | CRTSCTS | CS8 | CLOCAL | CREAD;
newtio.c_iflag = IGNPAR;
newtio.c_oflag = 0;
newtio.c_lflag = 0;
newtio.c_cc[VTIME] = 0;
newtio.c_cc[VMIN] = 0;
Again. The PC can send with this settings but not the dev_board.
One smaller question. Is it worth uppgrading to the new relese (R 2.0.0)? It
allready works perfecly (except serial) and I don't plan to use the new
opptions glibc provide.
