putchar redefinition

I wanted to write my own putchar function to be able to printf through serial port. I have inserted it into my source and recompiled. Howewer, it still redirects I/O to I/O debug window !?! What should I do? I have read the manuals back and forth, but cannot find any hints…I’m using Multi2K V3.5 Dejan

in appconf.h for your application change the following #define. #define APP_STDIO_PORT “/com/1” If not defined then the default is the debugger stdio

I’m not using GNU, but GreenHills Multi2K. So, this does not help… Dejan

Applies to GreenHills Multi2K with NetOS

I do not use NetOS…How is I/O performed in the barebone Multi2K run-time library? Dejan
