I have some existing GPRS modems that currently send a string to TCP port, this runs on a bespoke system for a client. It occurs to me that I might be able to received this info in to Ignition. I’ve looked at the TCP driver and this seems to be what I want, but as I understand it I have to connect to the remote device and this may not be possible.
With these modems the IP address is variable so rather than listern to the remote post I want to listen to the local port, I’ve tried to set the driver up using the localhost, 127.0.0.1 and the PC’s IP but although it says connected the wrapper log says cannot connect and I see the port as closed.
I’ve tried the UDP driver but still the port remains closed,
Port forwarding is OK and fire wall is off, any pointers?
