Explanation:

If the message "Error in TCPIP port options" repeatedly appears in a popup dialog box, check to see if Foxhound is unable to connect to a target database running on an earlier version of SQL Anywhere; e.g., version 6.

You may also see this message in the Foxhound Monitor page: -- [Adaptive Server Anywhere]Communication link failure: Communication error --

One possible explanation is the target database is not running.
