Configure DDB, and see if it reacts to the DDB hotkey. I would assume this, since interrupts are obviously working. Inside DDB, you even have a `ps' command you could use to examine the process status. If you're using a serial console, don't forget the option BREAK_TO_DEBUGGER. You can then use a BREAK condition on the serial line as the DDB hotkey. (BREAK is an out-of-band signal, you can generate it in Kermit by ^\B, or in cu by ~b.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
