<h1 class="topictitle1">VT220 workstation operating modes</h1>
|

|
|
<div><p>This topic lists several operating modes that are
|
||
|
|
supported while the system negotiates the VT220 workstation type.</p>
|
||
|
|
<p>These operating modes are as follows: </p>
|
||
|
|
<ul><li>VT200 mode with 7-bit controls is the default mode and uses the standard
|
||
|
|
ANSI functions. This mode provides the full range of VT220 capabilities in
|
||
|
|
an 8-bit communications environment with 7-bit controls. This mode supports
|
||
|
|
the DEC multinational character set or national replacement character (NRC)
|
||
|
|
sets, depending on the character set mode selected.</li>
|
||
|
|
<li>VT200 mode with 8-bit controls uses the standard ANSI functions and provides
|
||
|
|
the full range of VT220 capabilities in an 8-bit communications environment
|
||
|
|
with 8-bit controls. This mode supports the DEC multinational character set
|
||
|
|
or NRC sets, depending on the character set mode selected.</li>
|
||
|
|
<li>VT100 mode uses standard ANSI functions. This mode restricts the use of
|
||
|
|
the keyboard to VT100 keys. All data has a 7-bit restriction, and only ASCII,
|
||
|
|
NRC, or special graphics characters generate.</li>
|
||
|
|
<li>VT52 mode uses DEC private functions (not ANSI). This mode restricts the
|
||
|
|
use of the keyboard to VT52 keys.</li>
|
||
|
|
</ul>
|
||
|
|
<p>If VT220 mode is negotiated, then an initial operating mode for Telnet
|
||
|
|
client is selected using the ASCII operating mode (ASCOPRMOD) parameter of
|
||
|
|
the start TCP/IP Telnet (STRTCPTELN) or TELNET command.</p>
