| rs232_errors for USART2 |

Hi There,
How do I make a difference between rs232 errors on USART1 & 2? The variable rs232_errors seems to only represent errors from USART1, how do I get the ones from USART2?
Thank you,
Ron
That would be the distinction between RCSTA & RCSTA2 - I know that i can get acccess by using sft but because RCSTA is so nicely represented in a variable, is RCSTA2 represented as well? |

I tried below to recognize a BREAK but it doesn't seem to work properly :( Why not?
| Code: | #byte RCSTA2 = getenv("sfr:RCSTA2")
#use rs232(baud=BAUDRATE,parity=N,xmit=PC_TX,rcv=PC_RX,UART2,bits=8,stream=PC, ERRORS)
if (bit_test (RCSTA2, 2)&& ! input (PC_RX)) {
//BREAK
} |
RCSTA2 just keeps the value 0b10010000 and doesn't signal a FERR. Why not I'm wondering... :(
Thanks for hints! |
