Kurrel Posted November 12, 2007 Share Posted November 12, 2007 Hi everyone, I built a nifty code set that took a reading from a scanner and fed it into a database... this worked great, until I found the server was Linux (Ubuntu) and the code I was using would not co-operate on that. Is there any way to open the browser and click a button, having the local machine access it's com port 1 and read data from the device connected before feeding that back to the central database? Essentially, a web-driven monitoring system.

Kurrel Posted November 12, 2007 Author Share Posted November 12, 2007 I found that it might be possible to use fopen to access the port directly, but I don't think my linux knowledge is up to the task. I get the following : "Warning: fopen(/dev/ttyS1) [function.fopen]: failed to open stream: Permission denied in /var/www/LinuxTest/tindex.php on line 89" It's progress, and I'm trying to find out if there's further headway here or if I'm going the wrong way. Any help appreciated!
