while (1) {

		x = uart_getch();
		if (x >= 0) {
			if (x != 0x0d) {
				// not a CR
				uart_putch(x);							// echo the character back
				if (cmdpos < (sizeof(cmd) - 1)) {
					cmd[cmdpos++] = x;					// add character to command string
					cmd[cmdpos] = 0;					// and terminate command string
				}
			}
