###Using CC90HFE under Linux

Normally, the serial port is automatically detected by CC90HFE. But if this is not the case, you can still force the name of the serial port in the cc90hfe.ini file - that will be created after running and quitting CC90HFE - in <span style="background-color:#f0f0f0;padding-left:4px;padding-right:4px;padding-top:1px;padding-bottom:1px;">~/.config/teo</span> or in the root directory, facing the *`port_name`* key in the *`\[serial\]`* section.

If access to the serial port is denied, then use the Terminal command <span style="background-color:#f0f0f0;padding-left:4px;padding-right:4px;padding-top:1px;padding-bottom:1px;">sudo adduser $USER dialout</span> and restart Linux.

#####Using the command line

cc90hfe can be used on the command line. Use the '-h' or '- help' to display the help.

#####Uninstall

If the installation was done with the *`tar.gz`* file, simply remove *`cc90hfe`* root directory.

If the installation was done with the *`deb`* files, run <span style="background-color:#f0f0f0;padding-left:4px;padding-right:4px;padding-top:1px;padding-bottom:1px;">sudo apt-get remove --purge cc90hfe</span> in a Terminal.
