Are you talking about serial port programming for microcontrollers or about serial communication using windows/linux?

Yes i'm trying serial port programming in linux, i have read some posting here mention dev/tty. I'm still don't understand what this mean and how do you know com1 in linux? could you give me some briefly information how do you know ports in linux like com1,com2,etc. thanks.
 

Hello!

There is no ComX on Linux. Basically if you want to open a port, you do:

fd = fopen("/dev/ttyS0", RDWR);

or something like that (google is your friend), and then you can read and write in your
file handle. Of course you have to set the bit rate.
