If telnet to that TCP port does not work then EPICS won’t work. The fact that you can ping just means that the device exists.
Are you sure that port 1 is correct? On the devices I have used the first serial port is typically TCP port 2001 or 4001.

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?
