Hi,
I made a small program to send some data over Ethernet. It works fine.
Then, I wanted to send the data using some GPRS router that gives me an IP over the Internet, but that communication fails constantly.
I can easily ping the remote computer to where I want to send the data, but normally my communication fails to start - the TCP Open connection fails (normally with timeout error, but I also saw some error 1).
I already played a lot with timeouts and now I have wait forever on TCP Listen and I tried several in the TCP Open. Sometimes, the TCP Open goes ok and then the comunication runs very well between both parts, so my real problem is that it seems very dificult to start communication.
Did anyone had such an experience?
Any help is appreciated,
Paulo
