<li>When ONLINE(*YES) is used, specifying a wait time in the line description affects system IPL time. In such cases, system IPL time is influenced by the amount of time required to synchronously vary on the line or reach the wait-time value.
|
||
|
</li>
|
||
|
<li>The time required to vary on a line is the time it takes to:

<ul>

<li>Put tasks in place to manage the line
|
||
|
</li>
|

|
<li>Activate the communications I/O processor (IOP), including downloading the IOP model-unique Licensed Internal Code

<h3>Maximum frame size (MAXFRAME)</h3>
|

<p>Specifies the maximum frame (path information unit (PIU)) size that the controller can send or receive. This value is used to calculate request unit (RU) sizes. Since the maximum PIU size that the controller can send or receive is negotiated when system identifiers are exchanged, the maximum PIU size used at run time may be different. This value matches the corresponding value on the host system.
