Thanks Jeremy.
The issue is a known problem in the LwIP driver used by the
device manufacturer.?? That being said, since I have no control
over fixing the device, I was hoping for a way to force the
Crestron system to send things in one chunk.? I am using
HttpClient to send everything.? I hadn't thought about trying to
move strings created in S# back to S+, even Simpl, to send them
from those levels.? I figured Simpl and S+ were going to use the
same underlying http driver software so there wouldn't be a
difference.?
At this point the problem is moot.? Because of the issue I had to
abandon writing a driver for the product.
Thanks again

This is not HTTP Chunked Transfer Encoding, this is
a problem with the device expecting the entire request to appear
in the first packet received.? This is never a safe assumption
with TCP connections - you should expect anything from a
MTU-sized packet to one byte per packet.? Unfortunately, not all
devices are programmed correctly.? Jay are you using Crestron's
HTTPClient to send the request?? Have you tried using a string
in SIMPL+ to blast it all out in one chunk?? As long as it's
smaller than the MTU I would expect it to go out in a single
packet (though that's never guaranteed).
Thanks Alex.
I'm probably in the same boat.? But in my case, it is the
Crestron system that is sending messages chunked and
causing the issue.? I'm just hoping there is a setting, or
possibly a way in C#, to force the Crestron system not to
do this.
Thanks again

I ran into this with a display
driver I was creating a couple years ago. I was never able
to make things work properly. Essentially the device I was
working with would send all responses chunked. I worked
with several folks in ATSG on this and the end result was
that it was an issue with the device and no effective way
to work around receiving chunked data. I ran it up the
chain with the display manufacturer and they ended up
changing things on their end to fix it.
