Chapter 7: Installing Virtual COM Ports

7. Installiing Virtual COM Ports

The Virtual COM Port feature allows Windows platform software, using standard API calls, to be used in an Ethernet application.

The Install Virtual COM Port software adds a Serial Server (COM#) port to the computer. This shows up in the Device Manager. The COM number can be selected from a list of available numbers. For example, in a computer already having a COM 1 and COM 2, COM 3 to COM 254 are available for the Serial Server. We recommend that you select COM Port 5 or higher. The virtual COM port looks like a standard COM port to most Windows based applications. This enables the software to open a connection with the serial port located anywhere on the LAN/WAN. When using the virtual COM port, the Serial Server is configured as a TCP or UDP Server.

7.1 Virtual COM Port Installation

Step 1: From the Windows Desktop, click:

“Start —> Programs —> Serial Server”

The Search Setup window will appear.

Step 2: Select the “Search all reachable servers” checkbox, then click “OK.”

Figure 7-1. The Search Setup window.

The program searches the LAN for all available Serial Servers. When complete, the Found Server window appears and displays a list of the servers that were found.

Step 3: Select the Serial Server at the IP Address to be mapped to a virtual COM port, then click “OK.”
