Getting a new tty potGetting a new tty potPosted Jul 30, 2009 1:20 UTC (Thu) by corbet (editor, #1)In reply to: Getting a new tty pot by PaulWay Parent article: A tempest in a tty pot The real problem here, of course, is step 2. The current TTY interface is a little brutal at times, but it's standard and a lot of programs have been written to it. A new user-space API would be painful to bring in, and we'd still have to support the old one forever. Past history in this area is not greatly encouraging either. Solaris tried more-or-less what you suggest; the result was called "streams." If you've never had to deal with those, count your blessings.

The *problem* is also step 2, of course. The TTY layer isn't complicated
by its need to conform to RS232 or whatever. It's complicated by its horrendously arcane userspace interface (what is it, *two* chapters in APUE?), which is the very thing whose behaviour must be preserved.
