Digi RealPort Driver Package for Linux
Installation notes for the Debian source package
40002086_AE_debiansourcepkg.tgz

0. Make and switch to a clean working directory, e.g:
   mkdir work
   cd work

1. Unpack the Debian source package files for the driver:
     tar -xvzf 40002086_AE_debiansourcepkg.tgz
   to get:
     README
     dgrp_1.9.45.orig.tar.gz
     dgrp_1.9.45-1.dsc
     dgrp_1.9.45-1.debian.tar.xz

2. Build the Debian binary package customized for your environment
     dpkg-source -x dgrp_1.9.45-1.dsc
     cd dgrp-1.9.45
     debuild --no-lintian -b -uc -us

   This should create dgrp_1.9.45-1_amd64.deb in the
   parent directory.

3. Install the new Debian binary package
   # Note the leading "../" to fully specify the file pathname
     sudo dpkg -i ../dgrp_1.9.45-1_amd64.deb
     
To fully remove the installed binary package
     sudo dpkg --purge dgrp
