Julien,<br><br>The issue that fons brought up regarding mixed output lines does<br>raise another question: what do you do with programes if you have <br>problems? I take it most devo's want debug output, how do you get<br>it to them with your display?<br><br>Bristol has an option to redirect debug to a file, I think I might <br>see about getting that to work whilst having the CLI use another <br>file descriptor which is a dup() of the original stdout.<br><br>Nick.<br><br>"we have to make sure the old choice [Windows] doesn't disappear”.<br>Jim Wong, president of IT products, Acer<br><br><br><br><br><hr id="stopSpelling">From: nickycopeland@hotmail.com<br>To: fons@kokkinizita.net; linux-audio-dev@lists.linuxaudio.org<br>Date: Fri, 9 Apr 2010 23:07:23 +0200<br>Subject: Re: [LAD] Interface development for the blind (starting from Bristol)<br><br>

A text based interface is quite an abtraction<br>of something that has been written to be a GUI which means <br>debug output may well be useful. Since that does damage the<br>display, with or without brail, it does beg the question as to whether<br>it could be 'rewritten'.<br><br>It could be done with some IO redirection pipes, suitable code in <br>the 'raw' IO channel to understand where input came from using<br>a bit of extra select() in there to bring the channels back together <br>and apply suitable output depending on where the different CR <br>were, or that incomplete user input lines were rewritten after <br>each debug line? And then a bit of NL->CRNL for the raw mode <br>interface.<br><br>Not something I would want to code for a prototype but is <br>unfortunately something that could better be coded in advance<br>than bolted on the end?<br><br>Nick.<br> <br><hr>Hotmail: Free, trusted and rich email service. <a href="https://signup.live.com/signup.aspx?id=60969">Get it now.</a> <br /><hr />Hotmail: Trusted email with powerful SPAM protection. <a href='https://signup.live.com/signup.aspx?id=60969' target='_new'>Sign up now.</a></body>
