Deactivating The Asynchronous Communications Line On The System; Using The Console Service Functions (65+21) - IBM System i Manual

"Failure to display D1008065 and D1008066 automatically after calling the function" on page 108
When working with models that have a double row for the Function/Data display portion of the
control panel, calling the function 65 or 66, the control panel might not automatically display the
resulting system reference code (SRC).

If you know in advance that you will need a different console type, you can use the current console to
make the changes necessary for use with a different console.

Deactivating the asynchronous communications line on the system

These instructions apply only to local consoles directly attached and local consoles directly attached with
remote support enabled. Use these instructions to manually deactivate the asynchronous communications
line on the system.
1. If your system is not in manual mode, if the extended functions are not activated, or both, follow
these steps:
a. If your system uses a keystick, insert it in the key slot.
b. Place the system into manual mode by using the system's control panel.
c. Using Up and Down, select function 25. Press Enter.
d. Use Up to select function 26. Press Enter.
2. Use Down to select function 65. Press Enter.
If the deactivation is successful, the Function/Data window displays D1008065.

Using the console service functions (65+21)

Console service functions (65+21) are the emergency console recovery functions.
This function-set should be used only in circumstances where an unexpected console failure has occurred
and there are no other workstations available for recovery or debugging. Improper use may result in the
inability to use the intended console. Any hardware allocations or configurations will have to be
accomplished before using the console service functions (65+21). For example, if you are using a shared
IOP in an LPAR environment you can deallocate and allocate the resource from one partition to another,
if your hardware supports this method.
The console service functions (65+21) are standard control panel functions. They can be entered at the
physical control panel, any of the remote control panel connectivity types providing a graphical user
interface in Operations Console or using the LPAR menus on a primary partition. Since the first function
is a 65, which is the deactivation of the communications line used by the local console directly attached,
you may see the status of a connection using a serial cable go to Connecting console.
Important: To use these functions, the system must be far enough through the IPL for the code to run
properly. If a console device is available, you should use that console to perform any console
service functions, if possible. If a console device is not available, then perform these functions
only after a failing system reference code (SRC) has been displayed. This SRC typically is
A6005008.
