  4.2.4 Advanced Telnet operation  
There may be several concurrent Telnet sessions open. A user may switch back and forth between these sessions. The number of open sessions that are allowed at one time is defined by the session limit command.

To switch between sessions by escaping one session and resuming a previously opened session, use the commands shown in Figure .

A new connection can be made while at the EXEC prompt. The 2500 series routers are limited to five sessions.

Multiple Telnet sessions can be used and suspended by using the Ctrl-Shift-6, then x sequence. The session can be resumed by using the Enter key. If the Enter key is used, the Cisco IOS Software resumes the connection to the most recently suspended Telnet connection. If the resume command is used it requires a connection ID. The connection ID is shown by using the show sessions command.
