Check for keystroke

[Brian]

It took a little bit of coaxing, but I finally got it to run.  
Unfortunately, it still pauses while waiting for a keystroke.  Am I 
missing something?

Fixed code:
import termios, sys, os
fd = sys.stdin.fileno()
old = termios.tcgetattr(fd) # Old term info for restoration later
new = termios.tcgetattr(fd)
new[3] = new[3] & ~termios.ICANON & ~termios.ECHO
new[6][termios.VMIN] = 1
new[6][termios.VTIME] = 0
termios.tcsetattr(fd, termios.TCSANOW, new)

while 1:
        try:
                command = os.read(fd, 1)
                print command+">", #Echo manually
                if command == 'p':
                        termios.tcsetattr(fd, termios.TCSADRAIN, old) 
#Terminal back to line mode
                        break
        finally:
                termios.tcsetattr(fd, termios.TCSAFLUSH, old)
