Texecom JAL-0001 ComPort+ Digi Modem Port Pinout?

[RandomGrinch]

I may have to abort this project in it's current form and try ser2net on a Raspberry Pi.

I've found ser2net bulletproof for controlling the movement of a remote telescope mount.
If this works (with Max3232 presumably), I would definitely suspect the serial line levels of the ESP8266.

I've had a chance to setup a full test panel (Elite 64W) this weekend and played around with this project but I just cannot get the ESP8266 module to communicate with the panel at all. I thought I did previously but I think I was mistaken and interpreting the module RX/TX LEDs incorrectly.

I have probed the serial data being sent and it is arriving at the panel but the panel will simply not respond. I have tried almost every combination of settings on the panel comports and changed the IP port number (making sure to reset the com port each time by toggling to 'Nothing Fitted' and back) and a host of other settings (methodically) but the result is always the same.

There are reports of others getting these modules to work and it may be that I have built the esp-link software wrong but I have tried a few different units and they all work back to back with each other so as far as I can tell it 'should' work.

I may have to abort this project in it's current form and try ser2net on a Raspberry Pi.

I wish I could help in some way, but certainly keen to follow your progress!
