Com Port not working...

Post by kileinew » 2020/03/16 13:26:46


I installed a CentOS v6.9 community enterprise in one Lenovo M700 tiny PC. But the com port is not working. Is there a work around to troubleshoot/resolve this issue?

Your first step is to update to 6.10 by running yum update

You'll also need to review your logs, dmesg, /var/log/messages to see if there are any errors listed there to do with serial ports. If you have non-standard hardware the you may need to tell the serial modules about those.
