1  –  Parameters

 process-name

    Specifies the name of a parent process or spawned subprocess to
    which control passes. The process must already exist, be part
    of your current job, and share the same input stream as your
    current process. However, the process cannot be your current process
    or a subprocess created with the /NOWAIT qualifier.

    Process names can contain from 1 to 15 alphanumeric characters.
    If a connection to the specified process cannot be made, an
    error message is displayed.

    The process-name argument is incompatible with the
    /IDENTIFICATION qualifier.

2.1    /IDENTIFICATION

       /IDENTIFICATION
       /NOIDENTIFICATION (default)

    Specifies the process identification (PID) of the process to
    which terminal control will be transferred. Leading zeros can
    be omitted. The /IDENTIFICATION qualifier is incompatible with
    the process-name argument.

    If you omit the /IDENTIFICATION qualifier, you must specify a
    process name.
