Hi,
my /dev/ttyS0 port is not working - as far as I can tell. This is the only serial port on this machine (Dell tower)
This is the first time I have tried to use it on this machine and I cannot get it working. I have used minicom and it won't communicate to my external device.
On my laptop, which is also running Centos 5, the port works fine to my external device. I have the same minicom port settings (speed, baud,,etc), but it
Is there anything else I need to do to enusre the port is setup in the OS for usage?
I did try to do a setserial cmd, but got:
# setserial -a /dev/ttyS0
Cannot get serial info: Invalid argument
not sure if this helps, but something does not seem right....
thanks

Open firewall port on CentOS 7. Ask Question 300. I am using CentOS 7 and I have to ensure that ports 2888 and 3888 are open. I read this article but this did. Jan 30, 2018 - Configure your Arch Linux machine so you can connect to it via the serial console port. This will enable you to administer the machine even if it.
