I need to know can port 23 take up incoming connections other than
telnet requests when telnet is up and running?

That depends on if you have telnet up and running on port 23. If you have it
set up to listen to port 23, then no, I know of no way for something other
than telnet to use that port. If you move telnet to listen to a different
port, say 565, then a any other service that listens to ports could be
configured to listen to 23. In this case, you could have telnet running on
port 565 with a connection other than telnet could use port 23.

Basically, you can not have two different services using the same port, but
many services can be configured to listen to ports other than their
defaults.
