[comp.misc] dual port terminal

boyles@Software.Mitel.COM (Stephen Boyle) (03/07/91)

Presently I am working with a system whose interface consists of two
terminals (connected to separate computers). I need to replace these 
with a single terminal. I therefore need a terminal with 2 RS232 ports
and split screen capability (so that both screens can be viewed 
simultaneously). It must also have VT220 emulation capability. I am 
interested in both monochrome and color. I do not know if such terminals 
are available but I'm sure they must be. Any information on what's
available, with estimated prices if possible, would be greatly appreciated.

Thanks in advance,
Stephen.

When I needed to use one screen for two systems, I used a terminal emulator
program on a DOS machine. The program is Pereline from Pereline Data
Systems in San Jose, CA. Their number is 408-288-6612 and I think they
are getting ready for a new release.

Now that you can buy cheap XT clones for less than the price of most
terminals, this should be a very good way for you to go.

Although I am not familiar with model specifics, I know that several terminals
manufactured by Link Technologies have the ability for split-screen multi-port
access.  Whether they also support VT-220 emulation, I have no idea.

Unfortunately, I have no other information, either.  :-(

Of course there's always DEC's VT420 series (VT430? and VT440 also). 
Guaranteed compatibility, and I don't _think_ their prices are _too_ 
unreasonable.

Wyse Technologies makes the Wyse370 terminal which supports two serial
lines, split screen and color.  I don't know the price, or even Wyse's
phone number, but I used one for a while and liked it quite a lot.

AT&T has a 705 MT terminal that has two serial ports to accommodate two 
hosts, or a host and a printer, etc.  It has split screen capability 
via windowing.  In a dual host configuration each host connection would 
have its own window.  You can view the windows simultaneously or make both
windows full screen (in which case only one is viewable at a time, though
you can switch to the non-displayed window at the touch of a key).  
The 705 also has a VT220 emulation.  It is monochrome and comes in 
"paper-white" or amber.

The list price is $549.

You can call AT&T Computer Systems Sales and Information at 800-247-1212
and they can refer you to your local AT&T dealer for more information.

Link MC-10s do this, and I think the new Wyse 160 does, but not
sure on that one.

Link allows you to toggle between the window and if you go to a 48
line display you can see both at one time.  B

Both windows are kept active.

Here are some additional leads which I have not seen mentioned yet.
[Some of these are a little old (circa 1988) and may be dead ends.]

Their literature boasted about multiple set-up configurations (which sounds
really nice for a multi-host installation), including different baud rates.
The GP-29T listed for $1695, but it does Tek emulations, and lots of other
fancy stuff; perhaps they have a "slimmer model".
_ _ _ _ _

The following had even less emphasis in their literature about dual-host
capability, but my lit is old; maybe they have something now (and cheap?).

Falco also builds a terminal with up to 3 RS-232 ports with up to 6 windows.
You can toggle input to the terminal between windows. So, you can have
static data stored on the terminal. We had a few that would even do tek4014
immulation which I used to preview troff output.

I also tested the Links and Esprit. I just liked the Falco's better and
got about $100 savings per terminal. I was buying in quantities of 1-10
at a time with a verbal commitment to purchase 50 terminals minimum over
the next 6 months.
