Our hardware provides the capability to logout on hangup.  But, I had to
make sure my ~/.login file included the following in order to get processes
to let go.

stty hup -nohang

Portions of the 'stty' manual pages are below for consideration.

* stty - set terminal options
* 
* hup      When "stdout" associated with this process is closed for
*          the last time, hang up the terminal.
* 
* nohang   Don't send hangup signal if carrier drops.
* 
* -nohang  Send hangup signal to control process group when carrier drops.
