hello
i am trying to work with the serial port but i don't know which of the instruction had echo or not i am programing in C with the libary i am using is stdio.h how can i find out which of them had echo or not ??
output to the serial port : putchar puts printf
(there is echo at all when i sending out to the serial port ?!?!?)
input to the serial port : _getkey getchar gets scanf
thanks in advance mayer
You can look in the compiler Manual - it will tell you where to find the source for these functions.
Then you can inspect the source, and modify it if required...
there is echo at all when i sending out to the serial port ?!?!?)
Echo is something performed by the receiving side. If you send the data to a modem, then the modem may echo back your data. However, no transmit functions can echo any data.
thanks for the answer
that what i thoght
there is no problem with the instruction
putchar puts printf
