RealPort is a COM port redirector program that allows you to add and
remove virtual COM ports on your PC and update the RealPort software.
Virtual COM ports allow you to set up a connection between your PC and the
device connected to the serial port on your ES1A via an Ethernet network
connection using TCP/IP. If you will be using virtual COM ports
(configuring your serial port with the RealPort profile) you must use RealPort
to configure those ports on your PC. Once you have configured a new virtual
COM (VCOM) port using RealPort, application software can communicate
through that COM port as if it is located within the PC.
There are three steps to setting up a virtual COM port with RealPort.
1. Configure the ES1A with an IP address
2. Configure the ES1A serial port for RealPort (VCOM) mode
3. Configure the port itself using RealPort
Configuring the IP Address
See Chapter 3, Configuring the IP Address
