|
|
<dd>None

|
|
<dd><dl>

|
|
<dt>Operator Action
|
|
<dd>None.
|
|
<dt>Programmer Action
|
|
<dd>If it is deemed necessary for the guest operating system to issue DIAGNOSE 8 commands to issue panel commands, the <em>DIAG8CMD</em> with the <em>enable</em> argument should be specified in the configuration file.
