Problem in configuring Serial terminal

[pravinchanm]

Hai,

I am using linux centos and I am using termios.h to configure the serial terminal. I fixed the baudrate as 500000bps to communicate with the target by fixing the values as

options.c_cflag = 18b5
options.ispeed = 1005
options.ospeed = 1005

But the communication is not happening. But its working fine with the baudrate 230400bps. for that the configuration is 18b3 1003 and 1003 respectively...

I think you should make settings by using a combination of flags provided in the include directory (like options.c_cflag = B500000 | CRTSCTS | CS8 | CLOCAL | CREAD).

The options.ispeed and ospeed should be equal to 10005. You can check that by exploring the bits/termios.h file in the include directory.
