| How can I use 2 Uart simultaneously? |

Hello everybody,
I'll design a new project and I'm going to use 2 uart simultaneously.
I have a serious problem about the code to do this.
I use
| Quote: | | #use rs232(baud=9600, xmit=PIN_B2, rcv=PIN_B1, stream=PC) |
to set up a software serial communication and
| Quote: | | #use rs232(baud=9600, xmit=PIN_C7, rcv=PIN_C6, stream=PC) |
and Hardware serial Communication
Problem 1:
What need I do to set up the over serial Communication to work together in the same project?
Sorry about my English. |

specify different stream names in the #use statements:
| Code: |
#use rs232(baud=9600, xmit=PIN_B2, rcv=PIN_B1, stream=SOFT_UART)
#use rs232(baud=9600, xmit=PIN_C7, rcv=PIN_C6, stream=HARD_UART) |
and then use fprintf() to specify which stream to print to:
| Code: | fprintf(SOFT_UART, "This will be printed on the software UART");
fprintf(HARD_UART, "This will be printed on the hardware UART"); |

You can't. Use fputc() instead. | Code: | | fputc( 'A', stream_name); |

Thank you very much everyone, I was looking for for this example also.
It's work very well...
The only observation, the correct thing is:
| Code: |
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, stream=HARD_UART)
