BTW, as an experiment, I managed to program a stateless telnet server on a DSP. It doesn't do much (it echoes back what's sent to it, with a few character translations that show what other processing the DSP is doing) but what's interesting about it is that the DSP neither knows nor cares how many devices are connected to it. Ever seen anything like that?
Haven't really seen anything like that before. Sounds like it could be useful to test the status of a DNS through batch processes though.I can think of a number of ways to have a shell script query the DSP, and take actions based on what might be going on.
