Basics of Serial and TCP Communications

I have been recently introduced to Python and so far the learning curve has not been that steep. We use the Digi Connect Wan to connect our serial devices to a port server via modem emulation. Our goal is to break from that and move to TCP Socket communications where we can programitically handle more than one device per Digi Connect WAN. To do that there are obviously things we have to learn about the interaction between the Digi Wan Connect and python. We have gone through the self paced python learning and reviewd the digi python demo’s and examples but there is still some gray areas for us. I learn best from examples. Does anyone have an example of reading the serial port and then writting back to the serial port (handshake). Also if anyone is interested we looking some consulting services.

You can find this kind of examples in Digi ESP for python.
