I am home again and can do something serious with this. I tried to set a breakpoint at the rts after the copy and it seems like the last entry doesn't finish , i.e. rts is never reached. Can I (just for test) disable the 9th module? > I know I've asked this before, but isn't there a special code one can use to > cause a breakpoint in your debugger? (i.e. same A line instruction or > something like that). I don't know. It should be something that causes a exception. I get exceptions from the hw probing of VME bus. So perhaps a read from impossible address can do the trick here. Marcel, I will du a attempt with serial ports if above fails. _______________________________________________ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm
