uV2 Locks when exiting debug if set to accept data via COM port

Scott Kelley

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*/

    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. :-(
