### Requirements and Considerations

Read this section before beginning the RealPort driver installation.

- The Solaris RealPort device driver works with Solaris (SPARC) and Solaris (Intel) operating systems. The earliest versions of Solaris the device driver supports are Solaris 2.3 on the SPARC platform and Solaris 2.4 on the Intel platform. For the latest versions of Solaris supported, see the Release Notes.
- Installing the RealPort software on a Solaris host where RealPort has already been installed will overwrite the existing RealPort configuration on that host.
- The Digi RealPort device driver for Solaris is an installable device driver; the software development system is not required to create a new kernel.
