You *can* ftp tn3270, but I would suggest buying it by mail.
It is a fairly large body of code (something like 350Kbytes compressed);
additionally, it is useful for the University to have some idea of
tn3270 usage in the world (for when the University makes future development
The following is a canned message on how to acquire tn3270
via the mail:
New versions of the tn3270 and mset commands, used to logon to CMS from
unix, has been available since the late summer of 1987.
New features are:
o Error messages, in English, overlay a portion of the
screen when the user types an erroneous entry (invalid
control sequence, attempt to enter data in an "input
disallowed" field, etc.).
o Ability to "escape to shell". This, by itself, is
mostly useful in an MS-DOS (or non-BSD) system.
o An Application Programming Interface (API). This allows
programs, running under Unix or MS-DOS, to read and
write the 3270 screen, and to send keystrokes (3270)
to tn3270. This makes use of the "escape to shell"
feature. Included in the (beta) distribution is a
program which uses the API to receive files sent from
the IBM host (we don't supply the IBM side at this point,
and the rather stupid protocol is likely to change in
o Yale ASCII/7171/4994 "transparent" mode should now
be fully implemented. SAS-Graph, for example,
supports doing graphics to TEK terminals over
this interface. Locally, we use the X windowing
system terminal emulator (xterm), which provides
some TEK emulation, to display SAS-Graph graphics
on our workstations.
o Mset now prints out program function (PF) keys in
o Various bugs have been fixed.
To obtain the source for tn3270, send a check for $100.00 (US) payable
to "Regents of the University of California" to:
Campus Software Office

Specify that you are ordering tn3270.
This version will run under MS-DOS if the PC has the Ungermann-Bass
smart TCP board (NIU).
This version will compile under MS-DOS if you have: 512K of memory;
Microsoft C version 4.0; Microsoft MASM 4.0; the Ungermann-Bass "socket
emulation library"; and Polymake from Polytron (Hillsboro, Oregon).
