It is definitely port 4001 for this Moxa using TCP server mode. The attached screen shot from the Moxa shows this, and telnet from Windows to that port connects fine.
It uses port 966 as the Command Port, but 4001 for the data.
4001 is also what I use for the Moxas on our beamlines:
corvette:~/devel/CARS/iocBoot>find . -name '*.cmd' -exec grep -H 4001 {} \;
./ioc13GasLoading/st.cmd:drvAsynIPPortConfigure("serial1", "164.54.160.163:4001", 0, 0, 0)
./ioc13Win32/st.cmd:drvAsynIPPortConfigure("serial1", "164.54.160.50:4001", 0, 0)

./ioc13lab/serial.cmd:#drvAsynIPPortConfigure("serial20", "164.54.160.50:4001", 0, 0)

Subject: Re: problem connecting serial device with moxa 5150A
To me port 4001 is not correct, as I said in my previous post,
I use a Moxa 5150 on port 950 not 4001 and it works fine ...
see port list here 4001 is not in ...
http://www.moxa.com/support/faq/faq_detail.aspx?id=646
I've tried port 23 it works fine, 4001 doesn't work
hope it helps

I'm trying to help Sunny to connect from Linux to a serial port on a Moxa
box. It is not working, and I am stumped, so any ideas are welcome.
From Windows he can telnet to it:
when I telnet from windows
telnet 192.168.127.254 4001
It prompts a blank screen and for other IP or ports like 192.168.127.254
5064, 192.168.127.34 4732 etc. it simply says host not available so I think
port 4001 should be good.
When he connects it to Linux he can ping it:
ping 192.168.127.254
PING 192.168.127.254 (192.168.127.254) 56(84) bytes of data.

The firewall is disabled:

But when he tries to telnet from the Linux box it times out:

Trying 192.168.127.254...
telnet: connect to address 192.168.127.254<http://192.168.127.254>: Connection

Any ideas what could be causing this?
