Is it possible to apply Wireshark's telnet data filter to any ports other than 23? I've been trying to analyse traffic to several non-standard ports and I haven't been able to get it working.

You need to tell Wireshark, that the other port is to be decoded as telnet.

Example: The telnet server accepts connections on port 2323.

In Wireshark select a packet from the conversation on port 2323. Right click on that packet and select:

Decode As -> Transport -> TCP Destination (2323)

From the list of protocols select TELNET. Click on OK.

Now the display filter will also match on port 2323.
