6530 Telnet Protocol Definitions

[K.S.Lee]

Hi
Does anyone know of any resources on how to write a 6530 terminal emulator
over telnet? I have developed the serial (async) 6530 emulator, and need to
port it to run over TCP/IP telnet. I was wondering if there are user or
technical guides that describe the types of message exchanges that happen
during a typical block-mode session?

Cheers
KS

You should find what you need at www.telnet.org

Ouch... if this isn't the proverbial reinvention of the wheel! Why not just
use a commercial 6530 emulator? They aren't that expensive. Or is this a
practice exercise of some sort?

No, Dave, this is not a reinvention. This "emulator" allows the bridging
between a Win2K-based application and a Tandem-based Pathway application. I
know about Pathway SCOBOL IDS, RSC, POET, and all the good stuff. The
problem is that we don't own the Tandem host, and we need to have a
straight-through interface to it.

Using a "normal" terminal emulator will require us having to use
screen-scraping (which is restrictive) and have too many windows popping up
on the server, which by the way, MUST be running as a NT service. We wrote
one such 6530 data-stream emulator/parser service over async and need to
port to Telnet. We're not sure if there are special negotiation protocols
or formats between the Tandem's Telnet server implementation and the Telnet
client, though.

The spirit of this parser/emulator would roughly (and I do mean ROUGHLY)
approximate what the BETEX and J6530 would provide as part of their emulator
subsystems. Java is no good for us, and BETEX's pricing is stratospheric.

Any help?

You could save yourself a lot of time and get the free Web6530 terminal
emulator from Insession Technologies at WWW.INSESSION.COM.

Interesting application. Have you considered having the Pathway Terminal (since
you mentioned SCOBOL I assume that's what you're talking to) configured as a
CONVERSATIONAL terminal as opposed to 6350 or 3270? This would get you around
all of the 6530 protocol junk and leave you with a datastream to parse that
should look an awful lot like a Telnet session.

If that logic was employed universally, we would still be using Dante
or, worse yet, 6520's! The insatiable drive to build a better mousetrap
and our ability to store beer in glass bottles are what separate us from
the lower animals, IMO. And if a little intellectual orgasm results, so
much the better! We are human - this is what we do!

Yes.

I've actually done this, but for the 6510 emulation.

What you need to do is get a telnet OCX, you could certainly write
the telnet protocol from scratch using plain old Winsock, but you'll
save a lot of time and trouble if you buy the protocol.

Just do a Google search for "Telnet OCX" and a number of
products will come up.

Telnet implements a negotiation protocol (DO DONT WILL WONT)
I found that if I responded to all the DOs with WILLs and DONTs with
WONTs the Tandem end was happy.

When you establish a connection to the host you just feed any data
coming in from the telnet OCX as if it came from the serial data input
stream and anything typed needs to be routed to the telnet OCX rather
than the serial data output stream. It was pretty easy adding telnet
to my RS-232 emulation.

If you want more info, email me.

If this is to be a totally automated client you might want to convert
your connection to a control that can be added to an application. ie.
remove the screen and keyboard from the emulation and make them events
and methods respectively.

The ability to DRINK beer from glass bottles while spilling relatively little is
what separates us from the lower animals.

Hi Bob
I used to work with ACI here in Malaysia (yes, THAT very same country). I
even got to go to Base24 heaven in Omaha!

I'm familiar with WebGate, and I'm not aware that Insession is in the habit
of giving away free stuff. I tried searching for Web6530, but I can't seem
to find it. Anyway, we are unable to use a web-based emulator in our app.

Thanks & Cheers

Hi KS,
Yes it's true we are giving away Web6530 terminal emulator, free, gratis,
the link is http://www.insession.com/webgate/default.asp just go to the lower
right hand side of the page and there is another link that will take you to a
registration page, fill out the details and then you can download Web6530.
It is a fully supported product and even the support is free.
You only need a web browser running on the PC to access the emulator.

Regards
Bob
