/sys$common/syshlp/helplib.hlb TCPIP Services, TELNET, Suspending  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    While using TELNET, you can use the SPAWN command to suspend
    your current session and create a subprocess at the local DCL
    prompt. At the DCL prompt, you can then enter any number of DCL
    commands. To return to your suspended TELNET session (exiting the
    DCL subprocess), enter the LOGOUT command.
