1.1 root 1: Welcome to the new tn3270 - version 4.1.1.
2:
3: This version consists entirely of bug fixes to the August 1987 beta release
4: of tn3270. This version will now deal with CICS and VM/XA on the IBM
5: side, and with SunOS 4.0 on Sun 3's and Sun 4's.
6:
7: This version has been tested on various versions of BSD Unix, including
8: 4.2 and 4.3 (but there are never vanilla versions) and the post-4.3 systems
9: running at Berkeley. It has been tested on CCI's, Vaxen, Sun 3's and Sun 4's.
10: However, it doesn't necessarily work on all systems (nor has the testing
11: been as intensive as one might like).
12:
13: This version should build on any Berkeley-derived system.
14:
15: There are two alternate make files: ./makefile_4.2 and telnet/Makefile_ultrix.
16:
17: **** Try ./makefile_4.2 if you get compile-time errors, or get
18: "multiply defined" messages for "_putchar" from the loader.
19:
20: **** Try telnet/Makefile_ultrix if your make(1) utility doesn't
21: support VPATH. Also try this makefile if your ld(1) doesn't
22: support the -r flag correctly.
23:
24: The bad news is that I've had to drop MS-DOS support. The good news here is
25: that there are various versions available for MS-DOS (from FTP Software in
26: Cambridge, Mass.; from IBM; from Excelan; and probably from others). The
27: hooks are still there, as well as some code to update the screen. However,
28: I just haven't had the time to produce a fully integrated version that would
29: "just make". I suspect that a future release may have MS-DOS support back
30: in it.
31:
32: There is no Mac support. Contact Peter DiCamillo at Brown University if
33: you need a Mac tn3270.
34:
35: The main code change in this version is to what used to be called "telnet.c".
36: This is now replaced with a version of telnet (substantially what appeared
37: in the "4.3tahoe" release from CSRG) which is broken into separate files.
38:
39: Here is an overview of the directory structure:
40:
41: api/ General library of function needed by API
42: (and, to some extent, by the rest of tn3270).
43:
44: arpa/ Location of "telnet.h" (for non-4.3 systems).
45:
46: ascii/ Routines necessary to handle the case of running
47: from an ASCII-oriented system (ie: unix).
48:
49: ctlr/ The main part of the emulator. Handles 3270 scan
50: codes, 3270 data stream, 3270 display codes,
51: and EBCDIC. Also, the internal API function
52: lives here.
53:
54: general/ Some general subroutines and data structures of
55: interest to the emulator only.
56:
57: sys_curses/ System-dependent code for a curses-based environment.
58:
59: sys_dos/ System-dependent code for an MS-DOS-base environment.
60: Remember that this is included for your developmental
61: needs (ie: it doesn't work).
62:
63: telnet/ Where the telnet portion of tn3720 is built.
64:
65: tools/ Various tools. Most of these are used during the
66: build process. One (prt3270) is a debugging tool.
67: One (mkmake.y) is quite horrible, and attempts to
68: transform Unix makefiles into PC makefiles.
69:
70: utilities/ The source for tnrecv, which receives files
71: (fairly slowly) from an IBM host. We don't
72: include the IBM side, because we really aren't
73: happy with very much of it (except that it does,
74: sometimes, work). Hopefully, when we get past
75: the beta stage we will have more robust (and
76: complete) code to share.
77:
78: The fact that system dependancies are isolated should make it easy
79: to port to other systems. I would like to hear about problems porting
80: to new areas.
81:
82: In the August, 1987 README file, the following appeared:
83:
84: > WHAT IS NOT IN THIS VERSION (sigh):
85:
86: > 1) We don't have a native X version yet. I am waiting for X version 11
87: > (though this is mostly an excuse; I could have done version 10,
88: > but I haven't had the time).
89:
90: > 2) We don't process structured fields.
91:
92: > 3) We don't do 3270-style graphics (ala 3193, say).
93:
94: > The above three items WILL be in the next version, which should come
95: > along "any day now" (say 6 months) (but, they WON'T be in the production
96: > release of this version).
97:
98: The next piece of bad news is that none of the above have happened yet,
99: and I don't know when they might occur.
