I think that the minor detail that you are looking for is the difference
between the system (OS/400) or your program sending the data stream.

From the OS/400 view point, if the client want's to talk 5250 (like an
emulator) it makes a 5250 connection.  If the client want's to just make
a connection, it can be a sockets connection and then both the server
program (yours -not- OS/400) and the client can agree on any data stream
you wish.

And you are correct.  Your scenario could be batch.

From an OS/400 view point a socket connection is -not- a 5250
connection. It's a TCP/IP sockets connection.  What you send through it
(5250, 3270, 3451, HTML, XML, MSGQ, DTAQ, etc.) it doesn't know. 
Computers can't read ;)

Now software like Client Access, TN5250 use TCP/IP as the transport
protocol but they make a 5250 connection.  They pretend to be a 5250
hardware device.
