fcup-smsend: fixed bug in the handling of -W with no dest address argument The original code checked for argv[optind+1] when argv[optind] is NULL; on most systems this bogus code gets the first line of the environment, which is clearly not what we are after. Fixed the code to check argc instead.

main()
{
	uart_select_init();
	printf("Hello-world demo app running\n");
	print_boot_rom_info();
	for (;;) {
		putchar('=');
		if (command_entry())
			command_dispatch();
	}
}
