Hello net.oracle. We're in desparate need of the following: o) An X-based solution to 3270 emulation and file transfer, which can run over something similar to (or actually a) Mitek gateway or o) Unix and PC (under B&W NFS, or NETBIOS) solutions to the above. So far we have been spectacularly unsuccessful in doing this. We NEED to get from our environments here (BWNFS and Workstation) based to the mainframe environment! Any help or pointers appreciated. Pay-for software and harware are fine, ads are fine, free stuff is fine, anything we can get our hands on that WORKS. The tn3270 application does not work AT ALL, since our host system insists on sending "write structured field" calls, and we can't reply to them (the defines are there in the code source, but there's no code to back them up). We've been unsuccessful in locating a more recent version of the code. CUTCP (ie: Clarkson's CUTE Telnet 3270) doesn't work either, for the same reason. We're about to run out of options here; any help is GREATLY appreciated. We can do X11 on all the platforms, but we need a way to do the mainframe connectivity. Thanks in advance. Ads and all advice welcome. -- -- Karl Denninger AC Nielsen kdenning@ksun.naitc.com (708) 317-3285 Disclaimer: Contents represent opinions of the author; I do not speak for AC Nielsen on Usenet.

You might try to reconfigure your host so that it doesn't send a Write Structured Field. Look in the hostgen. Or check the Query Reply sent by your 3270 emulator to make sure that it's not telling the host that it supports WSFs. There's a bit in the Query Reply that indicates that (although it might be disguised as a "Reserved" bit -- make sure all "Reserved" bits are turned off). Good luck.

We ran afoul of one other gotcha: Run a VTAM trace on the failing session. Look at the query reply, and make sure it isn't lying about its capabilities. If not, then your host program may be making invalid assumptions about the terminal's capabilities, and acting as though some unspecified capability is there when it wasn't mentioned in the query reply, just because none of the standard terminals acts that way. Case in point: FTP Software's PC/TCP sends query replies saying only that it supports extended highlighting and colors, and no other extended datastream functions. PHOENIX 7.1.1 got that reply and assumed (incorrectly) that the device supported the 3270DS WSF, as well...and things broke. (This is fixed in PHOENIX 7.2, BTW.) If your application makes invalid assumptions, complain at your vendor. -- Jay Maynard, EMT-P, K5ZC, PP-ASEL | Never ascribe to malice that which can jmaynard@thesis1.hsch.utexas.edu | adequately be explained by stupidity.

You didn't say whether or not your Host is using VM or MVS...if it is VM, a quick and dirty solution is NOT to respond to the WSF Query Response Reply command at all....the host then internally assumes.... "Oh, a 3277 emulator, eh?" and treats you as a 3277 Model 2 device.... In VM, there are only about a thousand different places that need to be told NOT to send WSF and Extended Highlighting datastreams to a given device...and one of them will always be wrong unless you either answer 100% correctly to the Query Reply command, OR pretend you don't even support the command...

We were able to get this working -- sort of. We got ahold of a X-windows client that does full color and GDDM APA graphics (which is really nice)... and now, all of a sudden, it works (then again, this one understands WSF calls). The Mitek gateway, though, won't do auto-selection of terminal types, so we still have a problem. It's not as serious as it was before. Mitek says they're going to have a fix for the multidrop problem by Tuesday of next week.... if they do, and can provide automatic selection of terminal model (with a default for vt100 terminal clients) then perhaps we can get things resolved there as well. Then again, maybe not. Who really knows at this point. I've been asked not to release the source of the X-windows client for this yet, pending cleanup of the code and a real release. I'm sure we'll see it on the net eventually. Btw: It's is REAL good... I really do like it, even though it is a little rough around the edges at this point. -- -- Karl Denninger AC Nielsen kdenning@ksun.naitc.com (708) 317-3285 Disclaimer: Contents represent opinions of the author; I do not speak for AC Nielsen on Usenet.
