Output a Constant Signal/Voltage From a Serial Port

VERSION 1

Created on: Apr 6, 2009 6:53 PM by TylerC - Last Modified:  Apr 6, 2009 7:01 PM by TylerC

Functional Description

This example shows you how to output a constant voltage from your serial port.  This is done by using a break state property on a particular line.  In this example, we are setting the state for the DTR line; therefore, we get a constant five volts until we stop the application.  It is not recommended to use your serial port as a source, but the ability to constantly output a voltage is realizable.

 

 

Caveats and Additional Notes

Using your computer's serial port as a source can lead to damaging your computer, or worse by rendering it useless.
