hey there i have written a code that makes a tcp connection with a outside device. my server program collects the in coming data reads it a stores to file. the problem is that i am using the listen command and if i force a shut down i have to change ports. is there any way to make the program exit after it closes the port so i can run again and keep the same port. would like to know cuz i will be talking with a micro controller over network and its...

i have done things in python were i can collect data on usb ports. my question is i am sending data via wireless net work to my computer. is there a way to watch for the data coming in so that i can catch it and log it in a txt file. once i have the data i know how to log it but i cant figure out how to watch the internet port?
