telnetlib.Telnet class requires a callback so that the raw data that comes from socket can be processed first.

This will be useful for the compressed incoming data. Most of the MUD servers have MCCP V2 (byte: 86) protocol that send compressed data. But as for now. the only option is to create new class that inherits telnetlib.Telnet and override process_rawq()

As a general rule, your PR would have to include documentation (including a NEWS entry) and tests for the new functionality. Naturally, by itself it's not a guarantee that this suggestion would be accepted.

Made updates, tests for this old issue.

Note the telnetlib module is deprecated in 3.11 and set for removal in 3.13.

See PEP 594 – Removing dead batteries from the standard library and #91217.
