Thanks to input from mdavej and XARiUS, I found what I was looking for in terms of the technical details needed to control a Panasonic DMP-BDT110/210/310 unit using IP over a 802.11 network. Then I successfully controlled my device using a laptop or iPxx device thanks to Fulltopuk as well as TouchControl after some tweaks on HTTP POST made by its developer.
The technical details on the command format (again thanks to mdavej and XARiUS) can be found in the following post:
[Link: avsforum.com].
My TouchControl device layout has been designed and is available at that site, if needed:
www.touch-ir.com/. I have no affiliation to TouchControl other than I am a very impressed user (more on that in this post
[Link: avsforum.com]).
NOTE: Please note that STOP does not work on my DMP-BDT110 and I am looking for a command for the Display button. Also, if anyone knows of any Status commands for the Panny DMP-BDTx10s, that would be nice to know as well.
