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 COM1 and COM2, COM3 to COM 254 are available for the Serial
Server. It is recommended that COM Port 5 or higher be selected. The virtual
COM port looks like a standard COM port to most Windows based applications
which allows 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.
