You can have a daemon (telnetd, httpd, whateverd) listen to pretty much
any port. Check that it isn't one already registered or in use by using
'netstat -a' and looking in /etc/services. Man pages available for both.
The process of then connecting to that port with a client is different per
client (like "telnet host portnum") but generally pretty easy to figure
out.
As to what the cable co is actually scanning and blocking, and how, I
couldn't say.
