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?
