Hi,
I think the best will be to write a small C-program:
Here is the basic:
if (argc < 2) {
err(1, "Usage: ./a.out /dev/ugen0.1");
}
f = open(argv[1], O_RDWR);
if (f < 0) {
err(1, "Cannot open '%s'", argv[1]);
}
/* allow short transfers */
error = 1;
error = ioctl(f, USB_SET_SHORT_XFER, &error);
if (error < 0) {
err(1, "Cannot set short XFER\n");
}
error = 1000;
error = ioctl(f, USB_SET_TIMEOUT, &error);
if (error < 0) {
err(1, "Cannot set timeout");
}
error = write(f,"AT\r\n", sizeof("AT\r\n")-1);
while (1) {
error = read(f,buf,1);
printf("%c", buf[0]);
}
You have to modify the above before it compiles.
