uVision2 v2.10 When I include the following in my debug.ini file, everything works OK (properly receives data via COM1) until I attempt to exit debug mode, at which time it locks up . . . have to ctrl-alt-del to shut down uV2. MODE COM1 9600, 0, 8, 1 /*9600 bps, no parity, 8 data & 1 stop bit*/ ASSIGN COM1 <SIN >SOUT /*ASC output & input is done with COM1:*/ STIME = 0 /*ignore timing of simulated ASC interface*/
If you're running Windows NT or 2000 you can just use task manager to kill the hung uVision and restart it. Much faster than rebooting. If you're running Win9x, well... I remember something similar one time when I fiddled with the UART but I forget the solution (oh and I did solve by gum). For kicks, make sure uVision is the only program running and see if that makes a difference. I've noticed that uVision hangs sometimes if MS Outlook '97 is running. - Mark
I have also noticed that uVision will hang the system if it is simulating when the screensaver cuts in; it stops the system from recognising keystrokes or mouse movement to escape from the screensaver. On NT, the only way out is Ctrl+Alt+Del to get the Task Manager up - then everything's fine. On Win9x, it might well need a hard reboot. :-(
