Can someone point me at where I can find docs for the ptmx device driver
and the various support routines like grantpt(), ptsname() and unlockpt().
I would like to understand how X11R4 is talking to its local server
on a system configured for STREAMSCONN and att.
Thanks
Jim.

I found some info in the Prentice-Hall System V Release 4 volume titled something like "Streams Programmer's Guide." This included some stuff on pushable modules for line disciplines as well as basic info on the pseudo-tty ptmx/pts* master-slave pairs. ... rb

(Also note that the reason this is used for client/server communication in X is "it's there" - i.e., it's being used as the closest replacement for UNIX-domain sockets. S5R4 has UNIX-domain sockets, as well as a "local transport" in TLI; I don't know which, if any, of those are going to be the "standard" mechanism used for connecting to a local X server. Then again, the standard programmatic interface to X in the ABI, if there is one, may be through a dynamically-linked library, so that the standard is "call XOpenDisplay, etc." rather than "make a connection using this mechanism.")
