Hi guys, I'm building some hardware that spits out debug info on a regular basis, and I figured it'd be useful to have this data graphed on-screen. Making it keep track of the last "N" samples and draw them wouldn't be hard, except adding an LCD display is out of the question (takes up too many I/O pins). On the other hand, I have a perfectly good serial port which runs at a decent rate of speed (115200 baud), and Xterm can emulate a Tektronix 4014 vector terminal. Perfect... except I can't see an easy way to tie Xterm to a serial port instead of having it run an application. There's nothing in the manpage (admittedly I haven't read it all, just grepped it for a few obvious terms) and 'apropos' isn't finding anything useful. I've been told that tip(1) on BSD will do what I want, I just can't find anything similar on Linux... Thanks, -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/
