Hello All,
I am using MSC1212Y5 Microcontroller. It has two serial ports. I have directed printf to second serial port by changing putchar.c file in keil library. At the same time I am using first port for transmitting single characters only. i.e. 'T' ..'R'..etc. But whenever i try to use printf for both ports, of course by disabling one port for some time then it is not working..it sends data to only second serial port.
