How to get input from keyboard while doing other things at the same time?

I'm using C (gcc) and ncurses, to make a program that will be monitoring data coming from the serial port. The program has a big while, where it reads the data coming from the port and at the same time, it prints that info in the screen...

But the problem is here:

How can it read input from my keyboard, (since getch() freezes the program until it gets an input) and at the same time read info coming from the port?

Maybe I have to use another way (not the big while), so ideas are welcome!

c ncurses

Try select() or poll(). They both do the same thing, but with different interfaces. You give it a list of file descriptors, and it will wait until at least one of those descriptors is ready, then return and tell you which ones can be read from (or written to) without blocking. Check out the links for examples and more details.
