[comp.protocols.tcp-ip] VT220 emulation

702WFG@SCRVMSYS.BITNET (bill gunshannon) (09/19/90)

Does anyone know of a package that supports VT220 emulation on telnet
connections??  And before everybody jumps in and says FTP Associates,
the man who controls the purse strings has already said that solution
is too expensive.  I guess the only thing likely to change his mind is
if no other solution materializes.

Any info??

Bill:

One basic question--what is your environment?  Both server and client!  Any
marginal TELNET implementation will support a VT220.  What do you mean when
you say VT220 emulation?  Are you referring to a simple teletype style inter-
face, a VT52 interface, a 7 bit ANSI terminal interface, or a 8 bit ANSI
terminal interface?  Do you require DEC proprietary control sequences?  Do
you require multi-national character set support?

Without identifying exactly what you mean by "VT220 emulation" how can any-
one respond to your request information?  The meaning of "VT220 emulation"
is extremely dpendent upon your specific environment.

It seems that my request was not fully understood.  I am looking for a PC
version of TELNET with the ability to emulate a DEC VT220 terminal.  I need
both screen emulation and keyboard emulation.  This is intended to run with
packages like SCT Banner and ORACLE so it needs to be a pretty good copy
of a VT220.
I currently have NCSA Telnet.  It doesn't do VT220.  I have already suggested
putting it in our selves but there are other problems with the package that
make it less desirable.
I also have a package called MD_DOS IP.  It has VT220 emulation, however it
doesn't work correctly.  I have suggested fixing that but have not been
given the time or boddies necessary to accomplish it.
I am aware of FTP Associates and have been told it is too expensive considering
the number of copies we would need.
I was asked to gather information as to what alternatives there were.  I
personnally think fixing MD_DOS is the best bet but I don't make final
decisions.

I never really thought that people would think I was trying to build terminal
emulation into BSD UNIX.   :-(

    ....  Are you referring to a simple teletype style inter-face, a VT52

    interface?  Do you require DEC proprietary control sequences?  Do

If it has to replace ours, he needs an IBM PC DOS VT220 emulator with
7-bit and 8-bit support, the ISO Latin character set, keyboard and
display re-mapping and print screen support, built into a Telnet with
a built-in FTP server and multi-session capability.  Novell (Excelan)
offers VT220 in their product for the EXOS205, but I don't know its
capabilities.  Sun, IBM and 3Com had VT100 last I knew, I don't know
what Beame & Whiteside offers.  One could also get a VT220 emulator
from one of the Ascii emulator specialists and use it with an INT 14
Telnet redirector.  I don't recall any INT 14 redirector or VT220
emulator Telnets that are free...

Just for the record, I thought that the original poster was adequately
clear in what he was looking for.  From the wording of his message, it
sounded like he wanted a Telnet client that would emulate a vt220.  

I am not a protocol expert, but it is my understanding that "vt220" is
a specific DEC protocol that is fully defined.  If I am running a vt220
terminal emulator and log into my vax and do a SET TERM/INQUIRE it
should recognize me as a vt220.  If I am not emulating a vt220, it would
not recognize me as a vt220.

I agree that some emulators work better than others, but I don't believe
that a person has to regurgitate a complete spec to make a request to
the net.  So mellow out!

Thanks for all the comments I got from everybody.  I think the problem
is solved.  For those who find themselves in the same boat at some time
in the future (or present) the solution is (hopefully) FTP Software.
It turns out that the people who thought it was too expensive were dealing
with a quantity 1 price. When site licensing and Educational discounts are
taken into consideration, they become not only the best solution but also
very reasonably priced.

Thanks again for all the advice.
