Functions

Start

Gather date and send to server.

Text Input

Start and Stop text input modifies the file ATextInputA.txt in directory ../php using the script Count_Vote.php
Flags "Time", "Question", "UserID", "Vote", "Duration" and "Typ" are used.
"Typ" is filename. "Vote" = 1 means text input enabled.

A Client submit reads file via Read_Vote, checks "Vote" for enabled and submits text via Count_Vote.php.
If Enabled text input is added to Status section and then cleared. This reduces repetitive sending.

Questions: Multiple choice or text
