I'm looking for product information (hardware and software) and user recommendations for the following terminal/printer emulation problem: Need to provide IBM 3270 terminal emulation on up to 30 Xwindow workstations networked via TCP/IP Ethernet to a fileserver. Need to appear to the remote IBM Comm Controller as a 3274 Cluster Controller. Support up to 32 LUs, mainly 3270 terminals, and a couple of 3270 printers. Workstation hardware selection not complete, but may be Sun3s and SparcIIs. Prefer to have the dedicated SNA/SDLC line attached to the File Server with an intelligent comm board providing the cluster controller emulation, but will consider other configurations. |IBM |___|37x5|___|Sync |____ |Sync |___|File | |HOST| |Comm| |Modem| /__|Modem| |Server|-----Enet---- |Cntr| SNA 3274 | . . | Emula. WS1 WS30 I'd be glad to prepare a summary of responses or a submission to the FAQ. Thank You, Bob Irwin birwin@ficc.ferranti.com -- Bob Irwin <birwin@ficc.ferranti.com> Sugar Land, TX.

WS1 WS30 While doing a Unix to System/370 port of an AI engine, I used the SunLINK package to obtain the services of a timeharing house for the 370 time. The link was a lease-line LU2 from the Sun to the 370 and the Sun environment looked like ____ |Sync |___|File | /__|Modem| |Server|-----Enet---- | client WS's | .... Sun3/xxx running SunLINK This was quite satisfactory, although it did surface the 9600 baud limitation normally seen by all remote 3270's (ie slow screen painting). Recommend you contact your local Sun sales rep. ------ Jeff Beard jeffb@sharebase.com

There is no such limit. If your 3270 emulator will allow faster speeds, you can run at 64 Kbit or even higher...as long as the FEP has the proper hardware. Neither NCP nor VTAM care about the baud rate for 3270 in the gen....it is part of the link parameters...unrelated to LU or PU daffynishions. A lot of the smaller Unix boxen can't run faster, but a PC with a smart card or a Unix with smart front-end certainly can.
