I'm searching for a TELNET client software which emulates IBM 3270. I know there is a PD tn3270 package somewhere in an archive. I'm also able to get it, but before I ask somebody to download it for me, I have some questions. I try to connect our CAD environment (based on HP9000/3xx, 835) and the engineering environment (based on Sun) to our AS/400 (OS/400). IBM's AS/400 has a TCP/IP solution which supports FTP, TELNET etc. The TELNET server (also the client) on the IBM only supports ASCII streams, 3270 or 5250. For our applications we need at least the 3270 emulation. As I understand, the TELNET client must support 3270 emulation. In fact, the AS/400 expect a 3270 controller (I'm not sure about this) so the client has to simulate that. The user himself use his terminal as a 3270 terminal (with a quite different keyboard :-) ). Questions: - Does tn3270 have all this features I need ? - Is there another product available (as tn3270) ? - Is tn3270 usefull (speed, performance, keyboardmapping...) ? - Does tn3270 work with AS/400 TCP/IP (not only with VM/CMS) ? - Does tn3270 work with X-Windows(Openlook and Motif), Sunview and ASCII Terminals ? - Is tn3270 also usefull over 9600 Baud Modem ? (Terminal->modem->UNIX->tcpip->AS/400) - Native language support ? Thanks for all answers. (Do I get any ?) :-) Daniel -- Daniel Huber Tel. +41 31 52 96 64 Ascom Autelca Fax. +41 31 52 53 01 CH-3073 Guemligen email: dhuber@autelca.ascom.ch Switzerland uucp: uunet!mcsun!chx400!hslrswi!aut!dhuber

IBM's AS/400 has a TCP/IP solution which supports FTP, TELNET etc. The TELNET server (also the client) on the IBM only supports ASCII streams, 3270 or 5250. For our applications we need at least the 3270 emulation. I have heard rumors about the "TN5250" support being developed, but no standard has been published and for the moment it must be viewed as IBM proprietary (anyone from IBM want to comment or publish?). - Does tn3270 have all this features I need ? - Is tn3270 usefull (speed, performance, keyboardmapping...) ? That's hard to say: TN3270 does its best to make the terminal on your desk into a 327x device connected to the mainframe via co-ax. How well it succeeds depends on how well your terminal can be mapped to the specific model of 327x your application expects. A PC with the proper display adapter can do quite well for all kinds of 3278, and some varieties of 3279. 3179G is possible, too (talk to Mitek for that). Minshall's Unix TN3270 has a much harder job, in that it doesn't have a directly-addressable display and has to use curses and a keyboard-remapping scheme to transform random asynch Ascii terminals. Basic 3278-2 isn't too bad, but things like screen painting tend to be slow... - Does tn3270 work with AS/400 TCP/IP (not only with VM/CMS) ? Don't know, even about our own DOS product. I haven't yet heard of an AS/400 on the Internet that we could test against (any volunteers?). Either there would have to be something on the AS/400 which translated a 5250 data stram into a 3270 data stream, or you'd need AS/400 applications which understood 3270s. - Does tn3270 work with X-Windows(Openlook and Motif), Sunview and ASCII Terminals ? The curses output can be sent to a terminal emulator running in a window. It won't be too quick, but it works. I don't know of anyone who has re-hacked it to bypass curses and the emulator, but it could certainly be done, at the cost of marrying it to a particular environment. - Is tn3270 also usefull over 9600 Baud Modem ? (Terminal->modem->UNIX->tcpip->AS/400) I've used it that way. Reading or writing the whole screen will be slow, so watch out for applications for which this is a way of life... - Native language support ? Our DOS product has a user-loadable Ascii-EBCDIC translation table, and the screen and keyboard can be re-mapped. Minshall's original version would have to be customized in the source. I don't know what other vendors have done. James B. VanBokkelen 26 Princess St., Wakefield, MA 01880 FTP Software Inc. voice: (617) 246-0900 fax: (617) 246-0901

I haven't yet heard of an >AS/400 on the Internet that we could test against (any volunteers?). We are using FTP Software's TN3270 to telnet to an AS/400. It works pretty good; I wish it (TN3270) supported color or at least extended attributes (like underscore). The default 3270-to-5250 keyboard mapping (on the AS/400) is brain-damaged, but (somewhat) easily remedied with a user command. Also, it only does 24 lines. I also use FAL's telnet to log onto the AS/400. Extended color and highlighting work. Because of the weirdness in remapping the 3270->5250 keys, I wish I had a TN3720 that allowed its keyboard remapping to define more than one 3270 key to be transmitted with one PC key. The 5250 has 24 PF keys plus more than the usual 3270 attention keys: help, page up (roll down) and page down (roll up), some some functions have to be mapped to dual 3270 attention keys (PA1+PFx or PA2+PFx). A TN5250 would be nice for this reason.

Does anyone have an address or phone number for Mitek handy? The number for Mitek is (214) 490-4090. They are located in Carrollton, TX. We are using FTP Software's TN3270 to telnet to an AS/400. It works pretty good; I wish it (TN3270) supported color or at least extended attributes (like underscore). The default 3270-to-5250 keyboard mapping (on the AS/400) is brain-damaged, but (somewhat) easily remedied with a user command. Also, it only does 24 lines. I also use FAL's telnet to log onto the AS/400. Extended color and highlighting work. Our TN program [in ver 2.05 which was released a couple of weeks ago] does support extended attributes affecting color and highlighting. It also supports 32x80, 43x80, and 27x132 screen sizes, if your video card and monitor can handle them.

- Does tn3270 work with X-Windows(Openlook and Motif), Sunview and ASCII Terminals ? The curses output can be sent to a terminal emulator running in a window. Alternatively, get expo.lcs.mit.edu:contrib/x3270-1.2.tar.Z, Jeff Sparkes' X port of Robert Viduya's 3270tool.
