Here is a simple example for how to that using minicom. Next, press the reset button on the Arduino Uno to verify that the menu from the example program. To configure Minicom. None of this work: HW control not work at all, data transfer just stops (often at middle of byte when space state on TXD stucks!) and never continues after release of BUSY. Many of the flag names in this C-structure are almost the same (and do the same thing) as the arguments to the stty command. Minicom is a nice little text com program. write access, if this is a shared system then you should consider the security consequences of opening it up for. UNIX® has always had support for serial communications as the very first UNIX® machines relied on serial lines for user input and output. go down to Serial port setup and enter it. Reset the board, and wait for a moment. This is "hardware" flow control. Despite a user interface less modern than that of seyon, minicom is the more popular Linux communications program. stty -ixon disables XON/XOFF output control; stty ixon enables it.

After powering-off and restarting the board you will find that UBoot doesn't accept the input from the serial console. Toggling the Line Wrap Setting on Minicom. In my case, the master only has 4 UART pins: TX, RX, RTS, and CTS. With access to the UART, a user can see bootloader and operating system logs. If minicom doesn't see the LANG variable, it will try to fallback to. For example typing "echo test > /dev/ttyS1" at the command prompt should send the word "test" to the terminal on ttyS1 (COM2) provided you have write permission on /dev/ttyS1.
