### SplPdSetPort - Remarks

This function is called from the Workplace Shell. The port driver retrieves the values previously stored in OS2SYS.INI and displays a dialog box. Default values are used the first time if no previous values were stored in OS2SYS.INI.

When the user selects OK from the dialog box, the port driver stores the changed values back into OS2SYS.INI. The flag flModified is not set if the user did not modify anything or if the user selected CANCEL from the dialog box.

Note: The dialog should contain everything required for port initialization and termination.
