Hi,
This is regarding a query on the serial port redirection. I have done the changes in the files mentioned below but I find that the serial console redirection is not happening.
I am using FC11 as the OS.
1) /etc/grub.conf
Hi
So long since I used any of the serial ports, I've forgotten all., and where , to look on FC17 as things have changed with time.
I'm running an app which uses the serial port to put one of the lines high to use externally as a switch.
Howvever the app is complaing it cant open /dev/ttyS0.
What do I need to do to allow access to the serial port ?
the app is run at user level.
Thanks f
Hello,
I have been trying to set up communication between an MSP430 and my computer (running Ubuntu). I have had two problems with using the serial ports (one for each of /dev/ttyACM0 and /dev/ttyS0). Note that I doubt the problem is MSP430-specific.
/dev/ttyS0
The first problem arises when I tried to connect the MSP directly to the motherboard serial port.
In Linux I need to send a sequence of AT commands to a serial port on e.g. /dev/ttyS0, which has to wait for an OK answer before the next command is sent. I could imagine doing something like
echo 'AT' > /dev/ttyS0
echo 'ATS0=0' > dev/ttyS0
...
but this does not evaluate the answer from the device on that port.
I am looking for a command to see the process listening to a port, e.g. /dev/ttyS0 (with root rights on a Linux system). I can do that with
lsof /dev/ttyS0
but this is really too slow. Also, I cannot use the -p flag to make it faster.
I would like to do essentially the same using other resources of the linux system. Is that possible?
Is it possible to create a console using the SPI device (/dev/spidev0.0) in a similar way that you would create a serial console, or if not is this possible ??
Hi experts,
My old Ubuntu 11.10 crashed. I installed brand new 12.04. However my serial PCI card starts to give me problems. My card should give me 6 RS232 serial ports. However only 4 are working. I googled and I have found some commands to show the information on my serial ports.
I'm debugging a kernel module under VirtualBox with a guest and host OS as Ubuntu 10.10. I'm using the virtualbox serial port but I'm maxing out at the baudrate 115200. My grub config looks like this...
console=ttyS0,115200
Is there a way for me to change that setting in the guest OS so that the virtual serial port works at a faster baudrate? I've tried to use setserial.
Ubuntu 12.04 server x64
CyberPower Power Panel Business Edition 2.2.1
Does anyone know why PowerPanel fails to talk to the ttys0 serial port in 12.04? It works fine in 11.10 and 11.04. And it works well through a virtual box of 11.04 installed inside of host 12.04. But when installed directly on the 12.04 system, it fails to communicate with the serial port. Was something 'subtly' changed?
