Experimental Physics and Industrial Control System

Hi,
First, let it be known that I'm new to modbus.
My questions are as follows:
1) The download site has a link to V2.4, but what is there for
downloading only goes to V2.3;
nonetheless, there is V2.4 documentation. Where is it?
2) I have a read command that I only want to perform once, how can I
do so? It wants to
continue polling.
3) I can't find any sample code for writing. Specifically, I want
to write (and read) from the
analog output holding registers for my device (40001-4999) with
function 16 (and 3 for read).
Are there any examples from which I can glean? I would like to
see both the database entries
as well as the drvModbusAsynConfigure commands.
Thank you,
Pierrick
