How to type to minicom?


Hello there,
I have installed minicom in order to communicate with a serial device. I have configured it and now when i type "minicom" the console opens and I can receive text. The problem is I cannot write anything back from keyboard. I dont want to send a file or anything, just type back. Is there any setting for that? I would appreciate all help.

Perhaps you're wanting to enable 'local echo'?

Refer to post#3 of this thread...

Does this local echo blocks the reception somehow? Because with local echo I can indeed type the text in but I do not receive anything back as soon as I turn it on.

Local echo should not block receiving text from your device but without knowing anything about its command protocol or how it works it is impossible to say what is wrong.

Generally speaking its a simble debug interface for a linux device. To be more precise its an intel edison board. I am trying to interface with the uart link to login and etc. It works very well in Windows. The driver itself is FTDI usb to uart bridge.

I am not familiar with the board and from what I information I found setting local echo should not be required.

Just to verify that originally you saw the login message and prompt? That would confirm that you are using the correct serial device?

Yes of course, i did see everything including login screen. I just cant write anything without echo. With echo on the other hand i type in but the device doesnt respond, i see no data going back to me (only my echo)

You should look at the flow control settings, I think the choices are Hardware (RTS/CTS) and Software (XON/XOFF) in minicom.

As you say it works under another OS we must kind of assume that you are using the same cable and connectors, but check those if different.

Hardware flow control was on in minicom settings... I have not noticed that. Now it works. Thank you for help.
