I read the Digi release note for Digi Realport Driver package for Linux dgrp-1.9-35.i386.rpm but could not find the name of Digi Passport in it. We were first going to get the Digi CM but since it does not have 2 ethernet port we are now looking into Passport. Please let me know any link were we can get the answer
The RealPort driver will work with both the Digi CM and Digi Passport products. There is an option under the serial port configuration of the units to enable RealPort support.
I recommend using the latest beta candidate which supports newer kernel versions:
