I'm new to radare2 and reverse engineering, andHow can I can't see to see to figure out how to display any standard write in displayvisual mode.
For example if I run 'dc'dc command it runs the program normally and displays all the text normally. But if I enter visual mode with 'V< enter >'V< enter > and use 'S'S to run through the program it displays the output maybe a 1/10th of a second: 
Can I have it display it for longer, ORor enter a command and see what has been printed to stdout so far??
Thanks
