### Requirements and Considerations

Read this section before beginning the RealPort driver installation.

- At the time this document was created, the Linux RealPort driver supported the 2.0 and 2.2 kernels. To determine if a particular version of the Linux RealPort driver supports a particular version of Linux, check the release notes for that driver.

- At the time this document was created, the RealPort software did not support transparent printing, despite the fact that transparent print devices are created when the driver is installed. To determine if transparent printing is supported by a subsequent version of the Linux RealPort driver, check the release notes for that driver.

- RealPort utilities are located in /usr/bin/dgrp.

- Once the RealPort driver is installed, man pages are available for a number of the utilities associated with the package, including:

  `ditty-rp` |  | which sets and displays RealPort TTY device options
  `dgrp_cfg_node` |  | a tool used to add and remove Digi devices from the RealPort driver
  `drpd` |  | the Digi RealPort network daemon
  `dgrp.o` |  | the RealPort driver module. These are placed in /usr/bin/dgrp. The actual man page entry associated with the drgp.o module is dgrp.
  `dgrp_gui` |  | the Digi RealPort Manager for x-windows
