Re: application for barcode reader

Paul is correct, however...

If I were to guess (and it is a guess, because I've never worked with WiFi
readers, only ones that use wired connections), my first "guess" is that
what you want is built-in. If I were designing a WiFi reader, I'd furnish
it with an application that works either as a broadcast device (using UDP),
sending scan data that way, or as a TCP/IP server, which allows a connection
to be established from the "host machine" using Sockets, or perhaps
(similarly) a TCP/IP client that attempts to open a Socket connection to a
server on the "host machine."

After connection (TCP) the embedded packet protocol defined by the vendor
would be used to send data, and perhaps receive ACKs or commands from the
host.

If the device uses UDP, there might or more probably might not, be a
command/ACK protocol.

Again, all of this is speculation on my part. However, it makes sense (to
me) that it would work this way. If I am correct, then all that you have to
do is to get the documentation from your vendor on the specific mechanism
used, and then implement the corresponding service on your host machine.
