I am posting here since my responses to personal e-mail have all
bounced back, and this might be of general interest.

Doing a simple:

CloseDevice(..);
OpenDevice(..);

of a serial device will NOT drop DTR.  Doing instead:

CloseDevice(..);
Delay(50L);
OpenDevice(..);

will ALWAYS drop the DTR line.  This is all from "empirical" results
using the built-in serial device.  I have NEVER been able to have the
DTR line dropped on ANY of my modems WHITHOUT the 1 sec. delay.
