Assign Serial I/O to a PC COM Port
The ASSIGN command allows you to use a PC COM Port as input for an UART in the µVision3 simulator. If you enter the following commands, serial I/O is performed via the COM2: interface of your PC. The STIME variable allows you to ignore the timing of the simulated serial interface.
>MODE COM2 9600, 0, 8, 1 /*9600 bps, no parity, 8 data & 1 stop bit */ >ASSIGN COM2 <S0IN >S0OUT /*ASC0 output & input is done with COM2: */ >S0TIME = 0 /*ignore timing of simulated ASC0 interface*/
