Setting Baud Rate on Ubuntu 14.04

btsavage · 10-26-2015, 10:06 AM

I have a C++ application that requires the ability to dynamically change the baud rate of a serial port. My test setup is one machine with Ubuntu connected to a windows PC using TeraTerm. The send/recieve works fine and I can change the baud rate on the linux box using the stty from the command line. However, my calls to tcgetattr/tcsetattr are not returning error but do not change the baud rate.

Any advice?

Post your code. The proper procedure is tcgetattr(), cfsetspeed(), tcflush(), and tcsetattr()
