    I'm running some software here thats streaming out data from my serial port. It gives me an ip and port in which to retrieve the data. I've tried through IE but it didn't work, i assume its the router blocking the ports? (it uses 2101 or 2102)

    Whats the best way and safest way to collect this data stream through the internet? Sorry if this all sounds so vauge, i have very little expeirence in streaming data over the internet.

    Any help would be appreciated.

    What sort of data is it? IE prob won't work unless it's html output.

    It's GPS corrections, so its just numbers. Can be saved to a txt or a dat file and opened in notepad.
    8727.080449  13955.367697 -21045.033529     98.708604 13 14 10 355  P   P
PG04    -14.638703 -19699.831415  17610.739117    230.526010 19 17 15 296  P   P
PG05 -14998.963884  -4400.613830  21277.426578     -3.563901 11 12 10 340  P   P
PG06

    That's an example

    Ah yea GPS over a data stream.... had some experience with this.

    I used java to create a socket stream that connected to the data output of a GPS device to read the data. Then parsed it to extract the lat and long.

    Suppose the question is what do you want to do with the data? Save it? Display it?

    Well in the long run, it'll be accessed by other GPS units over GPRS. They can then use the corrections to get more accurate results for themselves. But for the moment, i just want to be able to listen to the corrections on another computer. Don't really need to be displayed, just saved to a file as they come in.

    The way we're currently doing it is by using a program called Ntrip server, it takes the information from the serial port and uploads it to a caster in germany. You can then dial into that caster from your unit and recieve those corrections but it's not as acurate as it could be if we took out the middle man.

    I'd like to know how to let the information be accessed with out having to open the ports on the router. (I assume i'll have to do that). Because i don't want there to be a security risk to our network.

    Thanks for your replies so far.
