OnDataAvailable is identical in all ICS components, does not matter which
client or server demos you look at.  

You have not told us what protocol your POS terminals are using,
specifically whether it is ASCII line oriented or binary packets, and
LINEMODE=TRUE will only work with the former.  

In practice, I rarely use LINEMODE=true even for line oriented protocols,
because sometimes those lines may be thousands of characters long and
exceed the buffers.  I usually use Receive or ReceiveFrom to accept data
into a buffer, and then loop through the buffer character by character
checking for line endings and other control characters and writing a
simple string for further processing.  The loop can check for long lines
and have a timeout if data stops half way through a line. 

For an example look at procedure TMagIpLog.SocketDataAvailable in the
component I recommended you use for testing yesterday, you are simply
trying to reinvent stuff that others have done already.
