Introduction

Step 5: Re-enter Server Properties to verify the changes have taken effect, or to view/change the configuration of other ports. Each port must be configured separately.

Install Virtual COM Ports on PC

Step 1: From the Windows Start menu, run the Install Virtual COM Ports utility included with the VLINX software,

Step 2: Search for all servers on the network

Step 3: Select a port and map it to an unused COM port (e.g. Port 15). Configure it for TCP protocol and the appropriate IP address (determined in the last section).

Check Communications

Step 1: From the Windows Start menu, run HyperTerminal

Step 2: Configure HyperTerminal to connect using the COM port configured in the last section (e.g. Port 15).

Step 3: Set Baud Rate, Data/Parity/Stop, and Flow Control to match the configuration of the serial device connected to the Serial Server serial port.

Step 4: Communications with the serial device should now be operational.
