Putting the Xiao esp32c3 to sleep

Okay, first of all, I want to thank everyone who responded to my initial post!

Assuming that sleep mode does to f-up the COM port connection, I uploaded the following:

int led = D10;

void setup() {
pinMode(led, OUTPUT);
esp_sleep_enable_timer_wakeup(2000000);
}

void loop() {
digitalWrite(led, HIGH);
delay(100);
digitalWrite(led, LOW);

esp_light_sleep_start();

}

Lo, and behold, I get an led that blinks every two seconds!
