On Centos / RHEL /Fedora Adding your user to the uucp group will give you access to the serial ports. to give your normal user access to the serial ports do the following as root usermod -a -G uucp <username> you can also do this with the GUI tool system-config-users this adds your normal user to the uucp group and gives your user access to the serial ports so that you can run com port applications as a user instead of root you may need to log your user out and back in again for this to take effect. > PS Note that Centos is a derivative, not a variant of Red Hat; Red Hat > would deny any responsibility for it. Having recently completed some redhat training this is true, however the redhat people work pretty closely with centos these days and Centos is not seen as a rival. Centos is based on the redhat Enterprise linux source code tree that Redhat publish under the terms of the GPL. Centos aims to be binary compatible with Redhat Enterprise linux > Red Hat commercialise open source > software by branding it and then charging for the use of the brand and > for support. Redhat operate within the parameters of the GPL licence and contribute a lot of paid for development resources to the linux codebase. They sell a commercially supported product, it is the support, the compiled binaries, Indemnity from litigation (SCO, MS etc) and branding that you are buying, not 'linux' > CentOs remove the Red Hat branding and bypasses the > support contract that encumbers commercially supplied copies of Red Hat > Linux. This is Something that the Centos people are perfectly entitled to do under the terms of the GPL. You are are also able if you so wish to download the entire RHEL source tree and rebuild your own binary compatible version 73 Brendan EI6IZ RHCE 85008029731335 -- Don‘t complain.
