 The N2 documents have plenty of errors,  don´t trust them fully.

The DTR signal will not be used with the regular serial 
tool,  maybe that's why you don't see any activity on that pin.
to use the modem tool and check again.   Also,  there are commands to 
modify the status of that pin with the regular serial tool,  I had to 
use them for the stowaway driver.

  HTH, but let me know if you need more details.
