Actually, I was speaking of hardware, like a little serial port extension with led's that flash when data is transmitted. I wrote the software using a read() call (before someone reminded me that cat will do that. Duh?), and I'm not sure software can do much else, since it should just be a nice little one way FIFO datastream (works for the mouse). The problem is that the read call just hangs waiting for data, which never shows up. Now I need to figure out if this is the digitizer or the computer that's having problems. -- Adam Carheden carheden@holly.ColoState.EDU
