Sender: owner-freebsd-questions@FreeBSD.ORG

I want to send/receive data to other computer thru serial port without modem.
So, I have connected COM1 to COM2 of itself and programed as follows.
 
Shell("stty -f /dev/ttyd0 clocal cread raw 9600 cs8 -parenb -cstopb"); 
Shell("stty -f /dev/ttyd1 clocal cread raw 9600 cs8 -parenb -cstopb");
fd1 = open("/dev/ttyd0", O_RDWR);
fd2 = open("/dev/ttyd1", O_RDWR);
childpid = fork();
if(childpid > 0)
    for(;;){
        ch = getchar();
        write(fd1, &ch, 1);
        }
else if(childpid == 0)
    for(;;){
        rc = read(fd2, &ch, 1);
        putchar(ch);
        }

But, if press any key, login message is displayed or nothing is displayed.
But, I don't want to use serial port for terminal, but only for data
communication.
How can I solve this problem ?

Regards.
