MV I/O RS232 Trigger Source DirectShow Filter
The MontiVision I/O RS232 Trigger Source Filter triggers its
output pins after receiving defined events from the specified COM
port. It supports multiple trigger output pins which are created
dynamically. On the creation of a pin, an event that triggers the
pin is specified. This filter can for example be used to capture
still images from a video stream on a specified COM port
event using the MV Image Grabber. It can be used with every
MontiVision filter that provides a trigger input pin.
