TSO terminals?

[John McKown]

Does IBM support TSO on any terminals other than VTAM LU2 or LU0 3270s? I
vaguely remember others such as 3767 and maybe 2740? What am I getting at? I
am mulling the utility of a non-VTAM terminal connection, such as directly
using a TCPIP telnet, not TN3270, connection. But perhaps using telnet/SSH
to a UNIX shell and the "tso" command will be sufficient.

I don't think you'll be able to set up the environment for running ancient 
typewriter devices for access to TSO as it was before the glorious dawn of 
SNA.

Thus even if you could find a 3767 or find some device or construct a 
configuration which behaves like a 3767 or a supported slight variation, 
there's 
no escape from SNA LU type 2, LU type 0 with the special protocol subset 
which supports the 3270 data stream - or - LU type 1 without function 
management headers - as documented in the following:

z/OS Communications Server SNA Network Implementation Guide, Appendix A. 
TSO/VTAM

Yes

You are correct except that the 2740 should have been 2741 - close!

Take care that, when you eschew the 3270 data stream, you eschew all that 
lovely "full-screen" stuff.

Oh - rhetorical - sorry!

The TSO/E Planning manual gaily mentions TCAM. It's not easy to get any 
more information about how to get your hands on TCAM these days. In any 
case I've a very faint memory that, at some point, in the - well, it's always a 
*distant* past, isn't it? - distant past, what was left of TCAM was to be 
supported by VTAM - so that's that!

Non-VTAM - and hence no SNA - is a no-no!

Since we are currently in the throws of being reminded of this tendency, I can 
already predict the quarters where this is likely to induce some incontinence!

Chacun à son goût !

Yes, LU1. I don't know whether there is a replacement for NTO, which
mapped s/s terminals into LU1.

So many TSO applications are 3270-dependent that I don't see the
utility, but there's certainly no reason that you couldn't log on with
a telnet-LU1 gateway if all you needed was line mode.

Interesting thought. A UNIX command which emulates LU1 instead of LU2.
Thanks! I think LU1 would be easier to emulate than the 3270 data
stream. LU1 would likely be similar to what I recall of the 3767.

I did a fast check. If I use a standard telnet client, not TN3270, I get a
line mode connection. Now I need to think if this will do what I want, or
just use REXX ADDRESS TSO.

Re: TSO terminals?

[Bruce Richardson]

Hello John,
   In our TSO signon CLIST (I know it should be Rexx ), at the very end, 
after re-allocating libraries (etc.), we use:

/*ALL DONE*/
FREE  FI(TEST)
ERROR RETURN
IF &SYSLTERM EQ 0 THEN EXIT
ISPSTART &PNL NEWAPPL(ISR)

The test on &SYSLTERM will EXIT if we are using Telnet (not TN3270) to 
signon. In Rexx use SYSVAR("SYSLTERM") instead of &SYSLTERM.

Best of luck.
