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*/
