Virtual Serial Port Method
1. Open QuickCam.
2. Select Configure
→
Serial Port Link to enable or disable the virtual serial port.
Some camera control tools can connect only to a Windows system serial port. To avoid
asking for changes from camera manufacturers, two serial COM ports in the PC can be
linked together to share the serial channel to the IP engine. Using this link, data written to
one port can be read by the other port, and vice-versa.
These linked serial COM ports can be either "virtual" or physical. To set up virtual ports,
use a virtual serial port driver. Some good virtual serial port drivers are available at:
http://www.softinfinity.com/ or http://www.virtual-serial-port.com/.
Alternatively, if a PC has two free physical serial ports, they can be connected together
and used as a pair, in the same manner as a virtual serial port driver.
The Serial Port Configuration dialog box allows you to attach the serial channel in
QuickCam to one port in a serial port pair, whether a physical pair or virtual pair.
Therefore, an external application needs simply to connect to the other serial port of the
pair to communicate with the camera.
