You mentioned that you "tried putting the system console on a telnet port," 
so you might have used the "SET CONSOLE TELNET" command (section 3.14 in 
the user's guide).  This separates the system console from the simulation 
console, leaving the latter attached to the initiating window.  But you 
still have to interrupt simulation with CTRL+E (at the simulation console) 
to enter the ATTACH command.

The "SET REMOTE TELNET" command, by contrast, connects a second, limited 
simulation console in parallel with the original simulation console.  
Commands entered at the remote console are performed internally by stopping 
the simulation, executing the command, and then resuming.  The simulator 
still pauses to execute the command, but only for the minimum time

You're welcome.
