Hello, ou there in IBM land. We're just starting out with IBm equipment here
after not having any IBM on campus for about 17 years. Please don't laugh,
I joined this group so I might learn something from the rest of you. Anyway,
here's my question. We'll have a 3720-1 controller, and a 3174-1L contoller,
and TCP/IP under VM/IS. Does anybody have the answers to the following:
- does IBM (or any one else) provide Ethernet hardware. Our SE is checking
and someone else thinks its an option in one of these controllers
- does anyone know about 3270 emulation for PC equipment over Ethernet
I'm looking here for probably a hsot and workstation product
We will be furnished with TCP/IP under VM/IS but I don't really know anything
about IBM's product. I doubt if this will help me.
Any and all assistance will be greatly appreciated.

I'm not an official IBM spokesman, but let's see if I can get close to the truth. Any mistakes are mine, not IBMs. TCP/IP on VM doesn't support either the 3720 or the 3174 controllers. Neither of those controllers supports Ethernet, either. The 3174 can be used on either coax (not Ethernet coax) or Token-Ring; on coax it supports real 3270 terminals; on Token-ring it supports PCs emulating 3270s and it supports SNA protocols. The 3720 supports various communications lines, async, SDLC, etc as well as Token-Ring; again, this box is usually used to support SNA connection of devices, but can be used for async or bisync support without SNA. It also supports Token Ring, but for SNA only. The TCP/IP for VM product can speak to several devices, but again not either of the ones you've got. If you've got a 9370 processor there's an Ethernet adapter that fits into the processor itself that TCP/IP can drive. On other processors, there's a device called the 8232 that hooks onto a S/370 channel and also goes onto one or more Ethernets and/or Token Rings; this device supports TCP/IP. This is the hardware that you'll need for TCP/IP on VM. As far as Ethernet 3270 emulators, the VM TCP/IP product provides a telnet server that can provide either 3270 or line-mode sessions via TCP/IP. There are a variety of telnet programs for many machines that provide 3270 emulation via telnet for different client machines. Hope that helps! Sam Drake / IBM Almaden Research Center

Kay, There are also several non-IBM Ethernet controllers which can be used with the (excellent) IBM TCP/IP for VM software. The cheapest (and also, in my opinion, the best presently on the market) is the ELC (Ethernet LAN Controller) from BTI (Bus-Tech, Inc.). BTI offers the ELC controller to BITNET schools for $5,900, with maintenance at $600/year. The ELC controller can operate in one of two modes: CETI (Continuously Executing Transfer Interface) mode or Standard mode (compatible with the Spartacus K200/K2000 and Nixdorf NECU controllers). The IBM TCP/IP for VM software supports the CETI mode. The Standard mode (which offers higher ELC throughput) needs an additional driver for the IBM TCP/IP for VM software. Drivers are available from David Lippke (LIPPKE@UTDALVM1) or Bob Knight (KNIGHT@PUCC). Lee Varian Princeton University

They also have a creative capability which interested us: they can let you use a 370's 3270-type terminal as a VT100. Let me know what else you find. We were going to use them because we wanted to take 3270's which we have all over the place, and provide a limited UNIX access. We have since abandoned this approach. Now, we are looking again, because we need FAST data transfer between UNIX and MVS. -- Kevin Kleinfelter @ Management Science America, Inc (404) 239-2347 gatech!nanovx!msa3b!kevin

Last I checked they were on Chennault Drive in Carrollton, TX. The
phone is (214) 490-4090.
