when deep sleep is executed, then the ** monitor link terminates** with:
> [toit] INFO: entering deep sleep for 2000ms
> Error: Port has been closed: Der E/A-Vorgang wurde wegen eines Threadendes oder einer Anwendungsanforderung abgebrochen.

import esp32

ENABLE_DEEP_SLEEP ::= true

main:

  restartReason := esp32.reset_reason 
  print "\n\n\n===> Restart($(restartReason)) <==="
