Reply to "Python code to issue TMCC, Legacy, and PDI Commands"

I am learning how to interact with the Base 3 over WiFi. I still don't know enough to say if I can dispense with the LCS Ser2 altogether. One interesting observation is that commands sent and received appear to be the ASCII representations of the byte sequences and not the byte sequences themselves. For example, the "keep alive" sequence one needs to send to the Base to keep the TCP/IP connection open is D1 29 27 DF (thanks to a new friend who sent me that info in a DM). I assumed I would be sending 0xd12927df, but instead, I have to send "D12927DF"!! This was a bit of a surprise and makes me a little worried the mechanism I'm using to connect is a debugging backdoor that may be slammed shut one day...

I've also modified my client code so that it requests a complete update from the server when started. This will allow all clients (deployed in separate control panels) to be up to date when booted up, should the server receive state before clients boot.

Back to it...
