Suspending the TELNET/iX Client 

You can suspend the TELNET/iX Client and return to the MPE/iX prompt by
using the Z command: 

     telnet> Z
     :

Suspending the TELNET/iX Client using this command is equivalent to
pressing the [Break] key.  The RESUME or ABORT command can then be used
on the program.
