T27 emulator for Mac (or Linux, with source)?

[Richard L. Hamilton]

Anyone know of a terminal emulator suitable to talk to
a Clearpath/MCP system, preferably free, and capable of
running on a Mac (or on Linux, if source code is included)?

I'd also consider a modestly priced (low two digits)
non-free one that was native on a Mac. I assume that
a Linux one would use either ncurses in a terminal window,
or X11; either would probably port to a Mac, but an X11-based
one would be a minor nuisance, IMO.

I've seen one that's a possibility (vseries.lerndal.org), but
find no mention of where the software can be obtained, and
astonishingly, no help from google. I've got an inquiry in...but
there may be better possibilities, and more people here that'd
know about them.

No, I don't want to fiddle with the web enabler stuff, not really.

[Hans Vlems]

Attachmate offers a product that includes a T27 emulator. But it fails miserably on two counts, it's for Windows and not anywhere near a two digit pricetag.
They might have a Macproduct though.

Will any of the available Windows products play nicely under Wine or

I admit I didn't think of trying to scrounge something free for Windows
and running it under Wine. No point in running it in Windows under Parallel,
since I'm trying to look at Windows as little as possible. :-) But with
Wine, I could wrap it up as an app, and it'd just be another window running
on my Mac's regular desktop, if something of an ugly one.

Or I could just try and figure out how to get Web Enabler working
(once I get the external network working), and live with that. :-)

[Graham Gold]

How about using the java applet version of WebEnabler(WebStation)?

Create using the wizard that comes with WebStation and Atlas/WebTS, then save off the web page files, have etc, and host locally - you don't need to have a web server, at least that was my experience on windows, I don't know about Macs.

Oh and did you see my reply about external networking in the other thread? I've just installed my MCP Express machine and will be configuring external networking again as one of the first things I do - so much easier than having to log into the desktop of the VM where MCPEx is installed to access it.

I don't have Mac, but those who do tell me you can set up Parallels in
such a way that you can have a Windows app running in a window on your
Mac desktop, without dealing with Windows otherwise.

[Paul Kimpel]

Actually, setting up WebEnabler for terminal emulation on a Mac is
easier than that. On the system where you set up MCP Express, go to the
install folder for WebEnabler, probably

C:\Program Files (x86)\Unisys\MCP\WebEnabler

Grab the Webstation.jar file (435KB) and transfer that to the
Applications folder on your Mac. On the Mac, double-click the .jar file.
That's it.

You'll get a warning that the configuration file could not be found, so
allow the program to open the default configuration. Then select File >
Properties... On the Advanced tab, at a minimum, enter the URL or IP
address of the MCP in the "Server Name" field. It would also be a good
idea to put something meaningful in the "Station Name" field, which will
become the basis for the station name used by COMS and CANDE. Then close
the Properties dialog and select Advanced > Connect. That should result
in a COMS log-in screen.

You will probably want to save (File > Save As...) the configuration so
you don't have to repeat this later. The configuration files apparently
go into the Unisys/WebEnabler folder under your user profile. The
default configuration file name is WebStation.cfg, but you can create as
many other configurations under different names as you wish.

The default transmit key is Return. You can reprogram the keyboard using
the Keys tab on the File > Properties... dialog. Ditto for font, colors,
and the finer details of emulation behavior.

Note that WebEnabler does not communicate using Telnet. It connects to
the MCP over port 3001 using a custom protocol that is implemented by
SYSTEM/CCF on the MCP side.

Another cheap emulation solution is to use a standard ANSI X3.64 (VT100)
client that connects over Telnet. The Telnet server on the MCP will
translate the Burroughs TD/ET/T27 control sequences to ANSI sequences
and effectively emulate a Burroughs terminal, with forms mode and as
much highlighting as X3.64 supports. This is not as nice as a full
TD/ET/T27 emulator, but it's usable. The default transmit key is Return.
Enter ESC ? to see a help page of keystroke commands.

This works with the standard Windows Telnet client. I just tried it on a
Mac with its Telnet client. It connects, but the forms-mode responses
from COMS are not formatted properly, so there's probably some
configuration of the client that needs to be done.

Thanks Paul,
Even easier than I thought, I had always created the config using the Wizard, even though I know the config is in the cfg. Old habits die hard!

Sort of; but when (usually accidentally) starting a Windows app
encapsulated in a Mac app like that, it does start Windows in
Parallels, but I've always had to log in to Windows (in the usual
manner), and then start the encapsulating app again, for it to
actually work. I suppose if one leaves the Windows VM up most of the
time, maybe has it autostart at login, it's no big deal, but IMO a
laptop, even maxed, doesn't really have enough RAM for that, not to
mention it probably eats the battery faster.

Ah. I have 16GB on my lappie, so I seldom struggle for RAM. And it
goes 5-8 hours on a charge unless I really cane it.

So do I, but if I run a Windows VM and Safari with a dozen tabs at
same time, I'm definitely going to be putting some pressure on memory.

I wish 32GB was an option, but AFAIK even on the latest MacBook Pro,
it isn't.

A running VM certainly wouldn't help the battery life any, but I
haven't had occasion to put to the test how much it would hurt (I
don't fire up a Windows VM every day, and very seldom while
traveling). If well behaved, and if the "travel mode" while on
battery between Parallels and Windows works well, I suppose that it
wouldn't hurt much.
