[RESOLVED] Help with TCP/IP program...Not sure what I'm doing

[MotoMan_Yz400]

Hello,
I'm having trouble with some TCP/IP work. Here's the bases of my program.

I have an application running on a computer that needs to be operated remotely. I've already worked up the ability to have my program control the application, so that part is done. I've been able to control the application through my program remotely via RS232. However my range and band speed is VERY limited.

My intent is to replace the slow serial port with a much fast ethernet port (via local network). I've played around a little with TCP/IP work, but with little, to no success.


What I am looking for:
1) I need my program at either end (server/client) to know and understand if the connection was lost and when it has returned.
2) Send instructions across ethernet between computers.


I've looked at some tutorials, which helped me alittle. However I cant seem to understand where to put in alterations to the sample code, to fit my needs.

I would post what I have so far, how-ever it's merely a carbon copy of online tutorials.


Could someone shed some light on this for me? What steps are needed to communicate 2 computers?


(P.S. - The final setup will actually be VB.NET app talking to a Python app, but I figured I'd work both ends in a language I understand first, then once thats working, then work on the Python side of things)

Yeah, I forgot there was a whole section of this forum dedicated to TCP/IP work.

I got something now, I think I understand it now. I was able to get files transfered at blazing speeds. Now it's time to work on the Python stuff.


Thanks everyone for the help!!!
