[comp.unix.questions] IBM 3270

jbayer@ispi.UUCP (Jonathan Bayer) (01/19/89)

We recently received a request from a customer for a termcap entry which
supports the IBM 3270 terminal.  This is out of my field, so I am
tossing it to the net.  Does anybody have a termcap entry which would
support this terminal?  Is this even possible?

Thanks.

Termcap entry may not be very useful since 3270 cannot use cbreak
and raw mode, I believe.  However, there is a utility tn3270 under
4.3bsd which might be of use. (man -k 3270 gives the folowing) :


map3270 (5) - database for mapping ascii keystrokes into IBM 3270 keys
mset (1) - retrieve ASCII to IBM 3270 keyboard map
tn3270 (1) - full-screen remote login to IBM VM/CMS

I have not used it however, but you might want to check it out.

I'll second that belief.

Yep, mapping FROM whatever you already have TO IBM 3270.  What the IBM
folks want goes in the opposite direction, and it's just not there.

In my limited experience, a 3270 is virtually useless on a unix
machine unless all you want is a dumb terminal.  The line-oriented
nature of the 3270 just does not lend itself to such applications as
one normally uses in the unix environment.  Not to mention the potential
hassle of EBCDIC/ASCII conversion.  (carets, square brackets, etc.)

Even when unix runs on IBM machines, the terminal of choice is an
ASCII terminal.  Sigh.

"tn3270" doesn't let IBM 3270s access UNIX, which is, I presume, what
the person who asked the question had in mind; it lets UNIX systems
access hosts that expect IBM 3270s to telnet into them - it's basically
a TELNET program and a 3270 emulator wrapped into one.  To quote from
the 4.3-tahoe man page (which, if you take it literally, implies that if
you actually *have* a Tahoe - CCI Power 6/32 and OEMmed versions and
derivatives thereof - it won't work, which is, I presume, not true):

	"Tn3270" permits a full-screen, full-duplex connection
	from a VAX UNIX machine to an IBM machine running VM/CMS
	giving the appearance of being logged in directly to the
	remote machine on an IBM 3270 terminal.

Does anyone have any pointers to a good IBM 3270 terminal
emulation test suite.  You know, something that will just
trash a poor 3270 emulator :-).  Both commercial or PD products
are ok.  I assume such a program would be IBM host based, but
I would be glad to consider other configurations.

Thanks in advance.
