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.
