Please read Build before going ahead and building the program. Also, if you have a problem, scan through FAQ; there are lots of interesting answers there.
Updates to x3270, as well as the current status of development and bugs, are available from the x3270 Web Page, http://www.geocities.com/SiliconValley/Peaks/7814.
Updates are also available on ftp.x.org and several X11R6 mirror sites, usually in the /contrib/applications/x3270 directory. Fixes are often distributed as patch files (you will need gnu patch to apply them) under the name fix.nn, e.g., the next fix to version 3.1.1 will be x3270-3.1.1.fix09.
Feel free to send comments, criticism, suggestions, complaints, etc., to Paul Mattes, Paul.Mattes@usa.net. Requests will be addressed as time and resources permit.
There is also an x3270 mailing list, which receives news about new releases. Send a message to Paul.Mattes@usa.net (it's a real person, with an automatic responses for certain subject lines) to get on the list.
