Interactive 2.2 asy/pty/poll bug

[Eric Gisin]

We have two program that work when used on console or a pty,
but not when use on an asy serial port. One is emacs (M-x shell) configured
with HAVE_SELECT and HAVE_PTYS. Both programs do a select
(implmented with poll in -linet) on the tty and the master side of
a pty.  Both programs have the same problem: output from the master pty
is not available until you give the tty some input.

This looks like a bug in the asy driver, or possibly ptys or poll.
The system crashed once in asyioctl().
Does anyone know if the fas driver will work? Does Interactive have a fix?
