<h2>Virtual Terminal APIs</h2>
|
||
|
|
|
||
|
|
<p>The virtual terminal APIs allow your iSeries<SUP>(TM)</SUP> application programs to
|
||
|
|
interact with an iSeries server that is performing work station input/output
|
||
|
|
(I/O).</p>
|
||
|
|
|
||
|
|
<p>A <strong>virtual terminal</strong> is a device that does not have hardware
|
||
|
|
associated with it. It forms a connection between your application and iSeries
|
||
|
|
applications, representing a physical work station (possibly on a remote
|
||
|
|
system). The i5/OS<SUP>(TM)</SUP> licensed program manages the virtual terminal, which
|
||
|
|
directs work station I/O performed by an iSeries application to the virtual
|
||
|
|
terminal. The virtual terminal APIs allow another iSeries application, called a
|
||
|
|
<strong>server program</strong>, to work with the data associated with the
|
||
|
|
virtual terminal.</p>
|
||
|
|
|
||
|
|
<p>In a distributed systems environment, the requesting program is called a
|
||
|
|
<strong>client</strong>; the answering program is called a <strong>
|
||
|
|
server</strong>. The client and server programs may reside on the same system
|
||
|
|
or may be distributed between two different systems. The server program
|
||
|
|
generally runs on behalf of (or in conjunction with) the client program.
|
||
|
|
Together, the server program and the client program allow a work station to be
|
||
|
|
supported as if the work station were connected locally.</p>
|
||
|
|
|
||
|
|
<p>You must specify a work station type when a virtual terminal device is
|
||
|
|
opened. A server program can select several different types of work stations.
|
||
|
|
See the <a href="QTVOPNVT.htm">Open Virtual Terminal Path</a> (QTVOPNVT) API
|
||
|
|
for a list of the types of work stations that are supported.</p>

||
