To monitor asynchronous hosts or perform alphanumeric paging, you must use serial COM ports. Historically, computers were configured with two COM ports on the back of the machine. Some newer computers no longer provide such COM ports. If your computer has no COM ports, or if two ports are insufficient for your needs, you can use a network-attached serial port expansion device to increase the number of COM ports.
A network-attached serial port expansion device is connected to the corporate network. CA Automation Point (which also must be connected to the corporate network) communicates to the serial port expander through TCP/IP socket connections. Serial devices are connected to the serial port expander. CA Automation Point communicates to the serial devices through the serial port expander.
To operate with CA Automation Point, one must configure the serial port expander to act like a native COM port. This typically involves installing driver software from that vendor. The driver simulates a COM port, but then sends all of the data that it receives to the serial port expander over the TCP/IP network.
CA Automation Point is configured and operated as if it were using a native COM port on the back of the computer. You must follow the installation and configuration documentation from the vendor of the serial port expander to setup the expansion device and the driver software associated with that device. Contact CA Support for information on a serial port expansion device that has been fully verified for use with CA Automation Point.
