RS232 : Can you have 2 stop bits using soft ccs UART ?

[stoppsm]

I have an application driving an RS232 device, it requires a word size of 8, parity = none, stop bits = 2.

Stops bits appear not to be configurable in the use rs232 () setup function, any suggestions would be welcome.


void fluid_control() { //

#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, parity=N, bits=8)

printf("RUN");putc(13);

} //

Requiring 2 stop bits is rather odd now days. But since a stop bit is the same as an idle line you could insert a simple delay after each character. Have printf() print to a function. That function consists of a putc() and a 1 bit delay. Note this gets much more complicated if you use a hardware UART.

Try using 9 bits of data and set the last bit high.

#use rs232(BAUD=57600,PARITY=N,XMIT=PIN_C6,RCV=PIN_C7,ERRORS,BITS=9) //hardware uart

#bit TX9D = 0x98.0 //the 9th bit for hardware uart tx

TX9D=1;
putc('x');



Good Luck
