z/VM: CP Commands and Utilities Reference - z/VM - IBM

If a real graphic display at the specified address is dedicated to a virtual machine,
you see something like this:
q 0bcd
GRAF 0BCD ATTACHED TO OLIVER 0010
Ready;
This message means the graphic display device at the real device number 0BCD is
attached to OLIVER’s virtual machine as the virtual device 0010. ATTACHED may
be replaced with BOX/ATTC, which means that although the device is dedicated to
a user, it is unavailable (usually because of a hardware condition).
If a graphic display device has a user logged on or dialed through it, you see
something like this:
q 08e0
GRAF 08E0 LOGON AS SVCDIR 0009
Ready;
This response tells you that the user SVCDIR is logged on through the graphic
display device at 08E0. The number 0009 is SVCDIR’s virtual console device
number.
If there are free graphic display devices at the specified addresses, you see
something like this:
q 08e1-08e7
GRAF 08E1 ENABLED, GRAF 08E2 ENABLED, GRAF 08E3 ENABLED, GRAF 08E4 ENABLED
GRAF 08E5 ENABLED, GRAF 08E6 ENABLED, PRT 08E7 ENABLED
Ready;
The responses for offline and boxed displays are in the same format.
Responses from Real Communication Lines:
If a real communication line is dedicated to a user, you see something like this:
q f0
LINE 00F0 ATTACHED TO OLIVER 0010
Ready;
This response means that the communication line with the real device number 00F0
is attached to OLIVER’s virtual machine as the virtual device 0010. ATTACHED may
be replaced with BOX/ATTC, which means that although the device is dedicated to
a user, it is unavailable (usually because of a hardware condition).
If there are communication lines that have users logged on at them or dialed
through them, you see something like this:
q fa fb
LINE 00FA LOGON AS DAVID 0009
LINE 00FB DIALED TO PVM 00F9
Ready;
QUERY (Real Device)
This response tells you that the user DAVID is logged on through the
communication line at 00FA. The number 0009 is the virtual device number of the
virtual console where DAVID is logged on. The second line tells you that the
terminal connected to communications line 00FB is dialed to PVM’s virtual device
number 00F9.
If there are free communication lines at the specified addresses, you see something
like this:
