Serial communication in Linux?

[Eureka]

I've been using 'screen' as my serial monitor in Linux. However, whenever I close out the terminal window, I cannot reaccess the serial device as it reports the resource or device as busy. Is there a way for me to free up the serial session so I can reconnect it without having to reset the device? Or is there a better serial utility to use?

I'm not familiar with that program, but this looks relevant...

Unfortunately, it seems like my screen doesn't want to do that. It doesn't close the connection properly and I can't reaccess it (says the port is busy). I'll have to look into it, but thanks.

"serial device"?

Serial device.


It's an ultrasonic sensor with a USB chip.

minicom might do the deed.

Check out a program called picocom, it's simpler to use than minicom, but that one works too and is fairly standard.
