I have a few questions concerning the usage of Chuck McManis's "raw"
and "cooked" utilities (recently re-posted).

I was wondering if it is possible to combine the raw mode with
waiting for signals on stdin's message port.  I modified Chuck's
testraw program to do the following:

   void main()
   {
       struct FileHandle *stdin_fh;
       struct UFB        *stdin_ufb;
       struct MsgPort    *readport;
       ULONG             signals,readsig;

       /* get message port for stdin */
       stdin_ufb = (struct UFB *) chkufb(fileno(stdin));
       stdin_fh  = (struct FileHandle *) (stdin_ufb->ufbfh);
       readport  = ((struct FileHandle *) (BADDR(stdin_fh)))->fh_Type;

       /* set stdin to CBREAK mode */
       if (raw(stdin) != 0) perror("raw");

       /* gather and dispatch input */
       readsig = 1 << readport->mp_SigBit;
       signals = Wait(readsig);

       if (signals & readsig) {
           /* read input here */
       }

       /* reset stdin back to normal */
       if (cooked(stdin) != 0) perror("raw");
   }


What happens is that "Wait" never returns.  Is the signal valid in raw
mode?  If I replace the "gather and dispatch input" segment with


       infh = Input();
       ok = WaitForChar(infh,1000000);
       if (ok)
           read(fileno(stdin),buffer,1);


It seems to work fine.  However, this is not what I want since eventually
I want to wait for input from other sources (i.e. intuition windows).
How can I do this?  Is there something similar to UNIX's "select()"
mechanism which somebody can help me with?


My second question concerns Chuck's testraw program and using "fputc()"
or "putc()".  I modified his while loop to be


       while ((c = fgetc(win)) != 'Q') {
           i = (i + 1) % 25;
           if (i == 0 ) fputc('\n',win);
           fputc(c,win);
       }


"fputc" put it somewhere, but not in the console device.  The same was
true with "putc".  Has anybody else tried this?


Thanks for any help you can provide.
