If the screenshot on the OpenWrt forum shows the full list of commands, then it is likely that not all data can be read on this device.
However, this is not the issue here. From the error message, it looks like the output from the Telnet server doesn't match the prompts expected by the client.
Packet captures of both the failing connection, and of a working Telnet connection using a regular Telnet client may help to fix this.
The full packet capture isn't actually needed, just the TCP payload is sufficient. Steps to get this with Wireshark (assuming the actual capture is already finished):
- Filter by "telnet"
- Right click a packet and choose Follow -> TCP Stream
- Select "Show data as: Hexdump", and save the output
Make sure to change the device's password before the packet capture, so the actual password doesn't end up in the capture!

Can you try the change in the branch zte-zxhn-h168n-v3
fixes the issue?

I'm wondering why the FEC and CRC error counters are missing. Could you provide a copy of the raw.txt
file? Maybe there is a way to fix this.

So this device misses many of the interesting procfs
files. And for the wan
commands the output is only printed to the kernel log, which cannot be accessed properly without dmesg
command.
However, the missing FEC and CRC counters was actually a bug which is now fixed. I also merged the Telnet fix into the master branch, so it is now included in binaries.
