Hi,

I have a device, that sends to a dedicated IP address and port combination 
(10.0.0.1:2036) a message at startup. It then expects a message back, 
specifying the port number of the host to send further messages to.
The device is connected to a second ethernet interface of a computer that has 
the 10.0.0.1 address assigned to it.

Can one use drvAsynIPServerPort for that? And if yes how do I connect a 
callbackfuntion, that gets called if there is a connection from my device. I 
need to reset the connection to the device in case of a reset/reboot of the 
device.
To communicate with the device I want to use drvAsynIPPort Which I would open 
in the callback function.

Regards

Jörn
