<h1 class="topictitle1">Dial mode (SNA)</h1>
|
||
|
<div><p>You use dial mode (that is used by Systems Network Architecture
|
||
|
(SNA) controller descriptions) to send a connection request to a remote device.</p>
|
||
|
<p>Dial mode starts when you vary on the controller
|
||
|
description. During the dialing process, the system polls the remote device
|
||
|
to determine if the device is ready to transmit. If the remote device is ready,
|
||
|
the connection process continues. Successful connection is still possible
|
||
|
even if the local and remote devices dial each other simultaneously.</p>
|
||
|
<p>These controller description fields control the frequency and duration
|
||
|
of the polling:</p>
|
||
|
<ul><li>LAN connection retry (<a href="rzajylancnntmrandlancnnrty.htm#lancnntmr_and_lancnnrty">LANCNNRTY</a>)
|
||
|
determines the number of times your system polls the remote device.</li>
|
||
|
<li>LAN connection timer (<a href="rzajylancnntmrandlancnnrty.htm#lancnntmr_and_lancnnrty">LANCNNTMR</a>)
|
||
|
determines the length of time between each poll.</li>
|
||
|
</ul>
|
||
|
<p>If the remote device answers the poll within the time that these parameters
|
||
|
specify, your system proceeds with establishing the connection. If not, your
|
||
|
system sends an inquiry message (CPA58E0 or CPA57EF) to the system operator
|
||
|
message queue. This message indicates that a connection attempt failed and
|
||
|
that the controller description is now in <a href="rzajuanswermode.htm#answer_mode">answer
|
||
|
mode</a>.</p>
