Install serial port
From xPL
Many devices are controlled over an RS-232 serial port.
CPAN serial port module
The xPL serial port device bases on the Perl CPAN Device::SerialPort module.
Open a terminal and login as root.
Update CPAN:
perl -MCPAN -e shell > install LWP > reload LWP > install CPAN > reload CPAN > install YAML > q
Check if the serial port driver is already installed:
perl -MFile::Find=find -MFile::Spec::Functions -Tlw -e 'find { wanted => sub { print canonpath $_ if /\.pm\z/ }, no_chdir => 1 }, @INC' 2> /dev/null | grep -i serial
Install the serial port driver:
perl -MCPAN -e "install 'Device::SerialPort'"
Alternatively, on Ubuntu:
apt-get install libdevice-serialport-perl
