Hi,

 

When I use “telnet” from my Linux machine:

  telnet 192.168.0.21 1

I also get connection refused. But “ping 192.168.0.21”, it works well.

 

I can’t find the “TCP Server Mode” attribute of the port of the NI Ethernet/RS232 convertor(4 ports) , and the port likely needn’t to be configured.

 

Then, Is the port number the convertor’s port num or the device port in the machine? how should I set the port number in drvAsynIPPortConfigure?
