ucom0 from dmesg means it is /dev/cuaU0 (and /dev/ttyU0), ucom1 -> cuaU1
and so on.
Then use "cu" or something if you want to interact with it manually.
"cu -s 9600 -l /dev/cuaU0" for 9k6 connections. (though 115200 is probably
nicer,
otherwise the Serial.print()s will spend too much time talking slow to the
computer
which also can handle lots faster speeds.

Hi,

this works for me
doas cu -s 9600 -l /dev/cuaU0
or simply
doas cu -l /dev/cuaU0

To more info, man cu

Considering the sketch you posted, you should have no problem using
cu(1), which is in base:

# cu -9600 -l/dev/cuaU0

To quit, type '~.' (tilde + dot). For more info about other escape
signals and what else is possible, please refer to the manual page: 

$ man cu

[Arduino] CLI serial monitor

[Olivier Burelli]

Hello,

i am playing with ARDUINO UNO on my 6.2 stable laptop.

I am trying to read the serial monitor message from the board.

from dmesg:
(...)
umodem0 at uhub3 port 1 configuration 1 interface 0 "Arduino SrlArduino Uno" 
rev 1.10/0.01 addr 3
umodem0: data interface 1, has no CM over data, has break
umodem0: status change notification available
ucom0 at umodem0

should i use cat /dev/DEVICE >> file.txt ?
or
(stty raw; cat > /home/me/received.txt) < /dev/device ?

--> which device is corresponding ?

does the information: "data interface 1, has no CM over data, has
break" means that OpenBSD can not receive data from the board ?

For example, i would like to catcg the strinf from the code below:
(...)
void setup(void) {
Serial.begin(9600);
// send the value of a string to the serial port (USB)
Serial.print("Hello world");
return;
}
(...)

Thanks in advance.

O.
