I am using a PortServer ll (fairly certain "without RealPort")
I am trying to connect to console of i.MX53 board running Ubuntu Linux. I have verified the board powers, runs U-boot then boots Linux. All the console traffic appears via a USB-serial dongle connected to host (OS X).
Yet, I am unable to connect with 'telnet 192.168.1.88 2001` to the i.MX53 console port.
The cat5 is connected to Port 1 on front of PortServer and to an official Digi TS Console Adapter part # (1P) 63000086-01 B. I also added a male-male gender changer to accommodate the i.MX53.
I performed part one of the diagnostics (described in Testing and Troubleshooting a PortServer guide
); and it worked as expected.
I made a loopback connector according to the Digi documentation. I am successfully able to telnet to IP address; then `connect 8` to port 8 which is configured for loopback operation. It works.
Please offer a suggestion for a fix or recommend troubleshooting tasks. That would be super helpful!
Here are some general configs and settings for port 1:

Many thanks to everyone who took the time to read!
It turns out the port is configured properly. I tried two other embedded Linux boards from different manufacturers (which did not require the gender changer). Those work fine.
I still do not know why the i.MX53 does not operate with this port.
As unlikely as it may be problem; the gender changer is the only other difference in datapath.
