S is wonderful. However, our AED512 graphics terminal hangs while initializing. The screen turns blue, as advertised, the LED'S flash prettily, and the keyboard stops responding till we push RESET. It hangs both when AED512 is supplied to tset (as opposed to, say, `dumb'), and when the aed512 driver is started in S, presumably because they use similar initialization strings. Has anyone else had this problem? The trouble doesn't seem to be in the terminal, as it works fine with S in tek12 emulation mode, and as an AED with our other (non-unix) computers. I have not gone through the assembly language code the initialization sequence pokes into the terminal yet, but it seems to be correctly bracketed with the relevant escape sequences. In the meantime, I notice that in $C/AEDSIZE there are 'echo -e ...' commands. Our versions of echo do not support an -e flag; does anyone know what it is supposed to do?
