calls, to be used in an Ethernet application.
calls, to be used in an Ethernet application.
The Install Virtual COM port software adds an ESP904 (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 is available for the ESP904. 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
ESP904 is configured as a TCP or UDP Server.
