				Hi,
 
 
I am aware that you can use two(2) #use rs232 directive together with stream.
 
 
How can I use the printf function such that I can specify which rs232 to use? like if u are sending to lcd display u have syntax stated below:
 
   printf(lcd_putc,"This is a sample text %lu",numb);
 
 
Anyone have done this method of printf function which you can be able to direct to a specific rs232 if two wer define in the program?
 
 
I need info, help or a code snippet will do....
 
 
Thank you.       |

				I'm quoting this from the manual:
 
 
 	  | Quote: | 	 		  
 
Syntax:
 
printf (fname, cstring, values...)
 
fprintf (stream, cstring, values...)
 
.
 
.
 
.
 
If fprintf() is used then the specified stream is used where printf() defaults to STDOUT (the last USE RS232).

You have to use fprintf if you want to specify streams. |
