Hello, I am trying to use stty to append a NUL character. I tried the following at a shell prompt: stty ofill nl1 That is en-el-one, when I ran this command I got back a shell prompt, but I don't know if it is working? I also had a couple of questions about stty: 1. Does stty reset to defaults when I exit the shell, in other words, if I typed in the stty command and then exited my shell, if I reopened my shell would the stty command still be in effect? I don't want to append two NUL characters? 2. I am trying to figure out what the stty ofill fill character, is for my mac mac os x 10.6? I know this is a little off-topic so feel free to respond privately. Sent from my iPhone
