The C15's CLI is not very intuitive, being a living relic of its DMS 
heritage.  There are different overlays you need to load to get into 
different administration areas of the C15.  I believe this comes from 
the era when RAM was limited and only one overlay/program could be 
loaded from the tape drive at a time. Much of that same paradigm still 
exists in the C15's current CLI. The CLI is accessible via serial and 
telnet, with no sign of ever being upgraded to use SSH.  There is no "up 
arrow" support.  That is, you can not press the up arrow key to get the 
previous command.  There is also no left/right arrow key support to 
assist you in modifying your current command.  Depending on your 
terminal settings, you may not have backspace support either.  There is 
no API, and it is very tedious to automate with expect scripts via the 
CLI.  Almost everything is in 3 or 4 character long keywords. You will 
eventually memorize many of them (CNAM, CND, CNB, CFW, etc), but you 
will forever be looking up many of these abbreviations in the manual 
(what is the difference between TR TTYP TERL, TRAL, TRAO, and TRAP?  How 
do these interact with the THGP or STN PICL setting?).

As for the GUI, as Shawn said, it is Java based.  As such, just assume 
it doesn't exist.
