2. Press Enter one or more times.
One of the following occurs:
• The message below displays:
FlashCONNECT <version> invalid message
where version is the FCService version running.
• A connect failed message displays indicating one of these possible problems:
• FCService is not running.
• FCService is configured to run on a different port.
• A firewall is blocking entry to the machine.
• Telnet connects but nothing displays, indicating one of these possible
problems:
• Another service (other than FCService) may be listening on the port.
• An older FCService version may be listening on the port.
