|
<P> Here are notes by brand name that were too specific to a certain
|
|
terminal to be put elsewhere in this HOWTO. If you have some info to
|
|
contribute on a certain terminal that is not covered elsewhere, it
|
|
could go here. Various models often have much in common so such
|
|
common information need only be written about once. It would be
|
|
nice if for each terminal model, there were a set of links linking to
|
|
most of the documentation relevant to that model (including escape
|
|
codes). But it hasn't been done. Note that some VT (DEC) manuals are
|
|
now available on the Internet. See and
|
|
<A HREF="#dec_">VT (DEC)</A>. Wyse put the information from its manuals on the
|
|
Internet but it can't be readily found now (2013). </P>

<P>Adds, which made the Adds Viewpoint terminal, was taken over by

Boundless Technologies in 1994 but they continued to use the "Adds"

<P> CIT terminals were made in Japan in the 1980's for CIE Terminals.
|
|
They ceased to be imported in the late 1980's. The company, CIE,
|
|
still made CItoh printers (in 1997) but has no parts for its
|
|
abandoned terminals. Ernie at (714) 453-9555 in Irvine CA sold (in
|

1997) some parts for models 224, 326, etc. but has nothing for the 80
|

and 101.</P>

|
|
</H2>
|
|
|
|
<P> Don't confuse IBM terminals with IBM PC monitors. Many IBM
|
|
terminals don't use ASCII but instead use an 8-bit EBCDIC code. It's
|
|
claimed that in EBCDIC the bit order of transmission is reversed from
|
|
normal with the high-order bit going first. The IBM mainframe
|
|
communication standards are a type of synchronous communication in
|
|
block mode (sends large packets of characters). Two standards are
|
|
"BISYNC" and "SNA" (which includes networking standards). Many of
|
|
their terminals connect with coax cable (RG62A/U) and naive persons
|
|
may think the "BNC" connecter on the terminal is for ethernet (but
|
|
it's not).</P>
|
|
<P>While this IBM system is actually more efficient than what is
|
|
normally used in Linux, terminals meeting this IBM standard will not
|
|
currently work with Linux. However, some IBM terminals are
|
|
asynchronous ASCII terminals and should work with Linux on PC's. The
|
|
numbers 31xx may work with the exception that 317x and 319x are not
|
|
ASCII terminals. Before getting an IBM terminal, make sure there is a
|
|
termcap (terminfo) for it. If their isn't, it likely will not work
|
|
with Linux. Even if there is a terminfo, it may not work. For
|
|
example, there is a termcap for 327x but the 3270 is an EBCDIC
|
|
synchronous terminal.</P>
|
|
<P>The 3270 series includes the 3278 (late 1970's), 3279 with color and
|
|
graphics, and the 3274 terminal controller (something like the 3174).
|
|
They may be used for both BISYNC and SNA. The 3290 has a split screen
|
|
(splits into quarters).</P>
|
|
<P>The synchronous IBM terminals don't connect directly to the IBM
|
|
mainframe, but connect to a "terminal controller" (sometimes called
|
|
"cluster controller" or "communication controller"). Some of these
|
|
controllers can convert a synchronous signal to asynchronous so that in
|
|
this case a synchronous terminal could indirectly connect to a
|
|
Unix-like host computer via its serial port. But there is still a
|
|
major problem and that is block transmission. See section
|
|
<A HREF="Text-Terminal-HOWTO-23.html#block">Block Mode</A>.</P>

</H2>
|
|
|
|
<P> These are antiques and represent the oldest terminals. They are
|
|
like remotely controlled typewriters but are large and noisy. Made by
|
|
the Teletype Corp., the first models were made in the 1920's and
|
|
predate the computer by over 30 years. Early models used
|
|
electro-mechanical relays and rotating distributors instead of
|
|
electronics. Their Baudot code was only 5-bits per character as
|
|
compared to 7-bit ASCII. See the book "Small Computer Systems
|
|
Handbook" by Sol Libes, Hayden Books, 1978: pp. 138-141 ("Teletypes").</P>

</H2>
|
|
|
|
<P> Digital Equipment Corporation (DEC) made the famous VT series of
|

terminals including the commonly emulated VT100. </P>

<P>In 1995 DEC sold their terminal business to Boundless Technologies.

Boundless went bankrupt in 2003 but emerged from bankruptcy in 2006 as

<P>VT220: Some have a BNC connector for video output (not for input).

Sometimes people erroneously think this is for an ethernet connection.</P>

<P>VT510, 520, 525: Supports full DTR/DSR flow control. Some are "low

|

<P>Wyse terminals were lower in cost than other brands and they captured

|
a major share of the market. There were concerns about the quality of
|
|
these terminals, especially the Wyse 50. But the large number of

failure reports (other than Wyse 50) may be due in part to the large

number of Wyse terminals in use.</P>

<P> Display adjustments (must remove cover): Brightness VR202, Height
|
|
VR302, Width VR101 (also affects height). If you want to use it in
|
|
Native Personality, then the arrow-key codes will conflict with the
|
|
codes used in vi (such as ^L). To fix this set "Application key mode"
|
|
with ESC ~ 3. This results in the arrow keys sending 0xd0 - 0xd3.
|
|
Due to a bug in the readline interface of the Bash shell, you need to
|
|
edit /etc/inputrc so that the arrow keys will work in Bash. See

|
<P>HINTS on use of WY-99GT User's Guide:
|
|
Note that much that is missing from this Guide may be found in the
|
|
WY-99GT Programmer's Guide. The VT100 emulation (personality) is
|
|
known as ANSI and uses ANSI key codes per p. A-10+ even though the
|
|
keyboard may be ASCII. A sub-heading on p. A-13 "ASCII Keyboard" also
|
|
pertains to VT100 because it has an "ANSI KEY ..." super-heading a few
|
|
pages previously. But not all ASCII keyboard headings pertain to
|
|
VT100 since they may fall under a non-ANSI personality super-heading
|
|
which may found be a few pages previously. Appendix H is the "ANSI
|
|
Command Guide" except for the VT52 (ANSI) personality which is found
|
|
in Appendix G.</P>

<H3>Wyse 150</H3>
|
|
|
|
<P> When exiting set-up using F12, hitting space changes "no" to "yes"
|
|
to save the set-up. The sentence to the left of this no/yes is about
|
|
"vertical alignment" and has nothing to do with this no/yes for saving
|
|
the set-up (confusing menu design).</P>
|
|
|
|
<H3>Wyse 185</H3>
|
|
|
|
<P>Has 10x20 character cells. Can emulate DEC VT320. Uses 45 watts power.
|
|
Later models were 185e.</P>
|
|
|
|
<H3>Low Emissions: -ES</H3>
|
|
|
|
<P>ES after the model number means low emissions: low magnetic field,
|
|
etc.</P>
