A number of related questions. They all refer to the Alcyon compiler.

How do you set stdin for raw input? I see in the library that there is
a routine called sggty, but can't find any documentation for it. By
the way, I know about Bconin and Cconin, but I don't want to go
changing old programs to use those.

Everyone says that Bconin ignores ^C ^S and ^Q, but I wrote a program
that just reads characters and writes them again, and when I run it
and then lean on the ^C key (so it auto repeats), the program still
stops with an interrupt. Am I doing something wrong?

How do you tell if stdin has been redirected (by a shell for instance)
before the program was started? Isatty definitely doesn't work, much
to my surprise.

Last question: how do you tell which version of the compiler you've
got?

Many thanks for any help on these questions.
