<p>The following example CL program sets the keyboard map for a 327x-type
|
||
|
|
workstation that is using Telnet to go to an iSeries™ server. This program maps the iSeries function
|
||
|
|
keys to their equivalent function keys on the 327x workstation. If you attempt
|
||
|
|
to run a CHGKBDMAP command from a workstation not in 3270 emulation mode,
|
||
|
|
you will receive the CPF8701 message. By monitoring it, the rest of the program
|
||
|
|
goes unused in these circumstances.</p>

<p>By storing this CL source as part of the QCLSRC file in library TCPLIB
|
||
|
|
as member CHGKBD, you can create the CL program CHGKBD into the TCPLIB library
|
||
|
|
by using the following CL command:</p>
|
||
|
|
<pre>CRTCLPGM PGM(TCPLIB/CHGKBD) SRCFILE(TCPLIB/QCLSRC)
|
||
|
|
TEXT('Change the keyboard mapping for 327x terminals') </pre>
|
||
|
|
<p>The CHGKBD program can then be called by anyone using Telnet to an iSeries server.
|
||
|
|
It can also be called automatically at sign-on time by specifying the CHGKBD
|
||
|
|
program for the Initial program parameter on the CHGUSRPRF command, or the
|
||
|
|
CHGKBD program can be called by the profile's initial program.</p>

<div class="section"><h4 class="sectiontitle">PA1 and PA2 keys on a PC keyboard</h4><p>The PA1 and PA2
|
||
|
|
keys do not appear on a PC keyboard. A keyboard map in your 3270 emulator
|
||
|
|
provides the function of these 3270 keys on a PC keyboard.</p>
|
||
|
|
<p>The default
|
||
|
|
3270 Telnet keyboard map uses these keys. Therefore, it is important that
|
||
|
|
you know where these keys are on the keyboard before starting a 3270 Telnet
|
||
|
|
session. This is especially important if you are planning to start a session
|
||
|
|
without changing the keyboard mapping. You should refer to your emulator documentation
|
||
|
|
for the keys or keystrokes required to provide these functions.</p>
|
||
|
|
<p>There
|
||
|
|
are some 5250 key sequences for which there is no supported 3270 key sequence
|
||
|
|
and, therefore, it is not possible to set these keyboard commands on a 3270.
|
||
|
|
These key sequences are:</p>
|
||
|
|
<ul><li>Field Plus</li>
|
||
|
|
<li>Field Minus</li>
|
||
|
|
<li>Erase all input fields</li>
|
||
|
|
</ul>
|
||
|
|
<p>The 5250 Field Exit Key function is performed on a 3270 keyboard using
|
||
|
|
the Erase EOF key and then the tab key.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Special circumstances</h4><p>When using Telnet 3270 full-screen
|
||
|
|
mode from the 3270 terminal and before the default mapping for the terminal
|
||
|
|
is changed, the keys PF1 to PF12 might be emulated by the key sequence PA1
|
||
|
|
PFx. Therefore, instructions like Press PF3 or Press PF4 should read: Press
|
||
|
|
PA1 PF3 and Press PA1 PF4, before creating a new keyboard map.</p>
|
||
|
|
<p>Depending
|
||
|
|
on the installation of the Telnet client for the host for example VM Telnet
|
||
|
|
client, when pressing PA1, the user might get the instruction <samp class="codeph">TELNET
|
||
|
|
command:</samp> at the bottom line of the display. If the system displays
|
||
|
|
this instruction type: <samp class="codeph">PA1</samp>, press the Enter key; move the
|
||
|
|
cursor to the command line; and press the desired PF key. In this case, the
|
||
|
|
following commands can emulate PF1 to PF12:</p>
|
||
|
|
<ol><li>Press PA1, get the Telnet instruction <samp class="codeph">TELNET command</samp> .</li>
|
||
|
|
<li>Type <samp class="codeph">PA1</samp>, press the Enter key.</li>
|
||
|
|
<li>Move the cursor to the command line.</li>
|
||
|
|
<li>Press the desired PF key.</li>
|
||
|
|
</ol>
|
||
|

<div class="note"><span class="notetitle">Note:</span> The <span class="uicontrol">Host Command Facility (HCF)</span> is
|
||
|
|
a feature available on System/370™ , 43xx, and 30xx host systems. This
|
||
|
|
feature enables a user on the host system to use applications on an iSeries server.
|
||
|
|
If you use HCF to connect to an iSeries server and then use Telnet to
|
||
|
|
sign on to another iSeries server from that iSeries server, you are in a 3270 full-screen
|
||
|
|
mode session. The keyboard maps twice, once for the initial HCF session and
|
||
|
|
once for the Telnet session. To use your PF keys the way you normally would,
|
||
|
|
you must change the keyboard mapping on both iSeries server. Make sure that you use
|
||
|
|
the same keyboard mapping on each iSeries server.</div>
