"catch" the call.  I.e. make the line in driver.c

   catch(open_port("telnet", 6047));

If you're not using networking, it won't work.  If you are, it will.  Either 
way the desired effect occurs.  

You want to be trickier, then actually assign the catch to a variable.  You
can then examine the error (if it does error) and find out if it was an error
based on not being able to open the port for some reason or if it was an error
because it doesn't know about open_port.

Possibly a more elegant solution can be thought of but this one will probably
do the trick.
